*skb)\n|{\n| struct p54_hdr *hdr = (struct p54_hdr *) skb->data;\n| struct p54_eeprom_lm86 *eeprom = (struct p54_eeprom_lm86 *) hdr->data;\n|\n| if (priv->fw_var >= 0x509) {\n| memcpy(priv->eeprom, eeprom->v2.data,\n| le16_to_cpu(eeprom->v2.len));\n| } else {\n| memcpy(priv->eeprom, eeprom->v1.data,\n| le16_to_cpu(eeprom->v1.len));\n| }\n| [...]\n\nThe eeprom->v{1,2}.len is set by the driver in p54_download_eeprom().\nThe device is supposed to provide the same length back to the driver.\nBut yes, it's possible (like shown in the report) to alter the value\nto something that causes a crash/panic due to overrun.\n\nThis patch addresses the issue by adding the size to the common device\ncontext, so p54_rx_eeprom_readback no longer relies on possibly tampered\nvalues... That said, it also checks if the \"firmware\" altered the value\nand no longer copies them.\n\nThe one, small saving grace is: Before the driver tries to read the eeprom,\nit needs to upload >a< firmware. the vendor firmware has a proprietary\nlicense and as a reason, it is not present on most distributions by\ndefault.", "title": "Vulnerability description" }, { "category": "general",

resolved:\n\nperf/core: Prevent VMA split of buffer mappings\n\nThe perf mmap code is careful about mmap()'ing the user page with the\nringbuffer and additionally the auxiliary buffer, when the event supports\nit. Once the first mapping is established, subsequent mapping have to use\nthe same offset and the same size in both cases. The reference counting for\nthe ringbuffer and the auxiliary buffer depends on this being correct.\n\nThough perf does not prevent that a related mapping is split via mmap(2),\nmunmap(2) or mremap(2). A split of a VMA results in perf_mmap_open() calls,\nwhich take reference counts, but then the subsequent perf_mmap_close()\ncalls are not longer fulfilling the offset and size checks. This leads to\nreference count leaks.\n\nAs perf already has the requirement for subsequent mappings to match the\ninitial mapping, the obvious consequence is that VMA splits, caused by\nresizing of a mapping or partial unmapping, have to be prevented.\n\nImplement the vm_operations_struct::may_split() callback and return\nunconditionally -EINVAL.\n\nThat ensures that the mapping offsets and sizes cannot be changed after the\nfact. Remapping to a different fixed address with the same size is still\npossible as it takes the references for the new mapping and drops those of\nthe old mapping.", "title": "Vulnerability description"

Also allocate and copy hash for reading of filter files\n\nCurrently the reader of set_ftrace_filter and set_ftrace_notrace just adds\nthe pointer to the global tracer hash to its iterator. Unlike the writer\nthat allocates a copy of the hash, the reader keeps the pointer to the\nfilter hashes. This is problematic because this pointer is static across\nfunction calls that release the locks that can update the global tracer\nhashes. This can cause UAF and similar bugs.\n\nAllocate and copy the hash for reading the filter files like it is done\nfor the writers. This not only fixes UAF bugs, but also makes the code a\nbit simpler as it doesn't have to differentiate when to free the\niterator's hash between writers and readers.", "title": "Vulnerability

the Linux kernel, the following vulnerability has been resolved:\n\nrose: fix dangling neighbour pointers in rose_rt_device_down()\n\nThere are two bugs in rose_rt_device_down() that can cause\nuse-after-free:\n\n1. The loop bound `t->count` is modified within the loop, which can\n cause the loop to terminate early and miss some entries.\n\n2. When removing an entry from the neighbour array, the subsequent entries\n are moved up to fill the gap, but the loop index `i` is still\n incremented, causing the next entry to be skipped.\n\nFor example, if a node has three neighbours (A, A, B) with count=3 and A\nis being removed, the second A is not checked.\n\n i=0: (A, A, B) -> (A, B) with count=2\n ^ checked\n i=1: (A, B) -> (A, B) with count=2\n ^ checked (B, not A!)\n i=2: (doesn't occur because i < count is false)\n\nThis leaves the second A in the array with count=2, but the rose_neigh\nstructure has been freed. Code that accesses these entries assumes that\nthe first `count` entries are valid pointers, causing a use-after-free\nwhen it accesses the dangling pointer.\n\nFix both issues by iterating over the array in reverse order with a fixed\nloop bound. This ensures that all entries are examined and that the removal\nof an entry doesn't affect subsequent iterations.", "title": "Vulnerability description" }, { "category": "general", "text": "The CVSS

resolved:\n\nxfrm: Duplicate SPI Handling\n\nThe issue originates when Strongswan initiates an XFRM_MSG_ALLOCSPI\nNetlink message, which triggers the kernel function xfrm_alloc_spi().\nThis function is expected to ensure uniqueness of the Security Parameter\nIndex (SPI) for inbound Security Associations (SAs). However, it can\nreturn success even when the requested SPI is already in use, leading\nto duplicate SPIs assigned to multiple inbound SAs, differentiated\nonly by their destination addresses.\n\nThis behavior causes inconsistencies during SPI lookups for inbound packets.\nSince the lookup may return an arbitrary SA among those with the same SPI,\npacket processing can fail, resulting in packet drops.\n\nAccording to RFC 4301 section 4.4.2 , for inbound processing a unicast SA\nis uniquely identified by the SPI and optionally protocol.\n\nReproducing the Issue Reliably:\nTo consistently reproduce the problem, restrict the available SPI range in\ncharon.conf : spi_min = 0x10000000 spi_max = 0x10000002\nThis limits the system to only 2 usable SPI values.\nNext, create more than 2 Child SA. each using unique pair of src/dst address.\nAs soon as the 3rd Child SA is initiated, it will be assigned a duplicate\nSPI, since the SPI pool is already exhausted.\nWith a narrow SPI range, the issue is consistently reproducible.\nWith a broader/default range, it becomes rare and unpredictable.\n\nCurrent implementation:\nxfrm_spi_hash() lookup function computes hash using daddr, proto, and family.\nSo if two SAs have the same SPI but different destination addresses, then\nthey will:\na. Hash into different buckets\nb. Be stored in different linked lists (byspi + h)\nc. Not be seen in the same hlist_for_each_entry_rcu() iteration.\nAs a result, the lookup will result in NULL and kernel allows that Duplicate SPI\n\nProposed Change:\nxfrm_state_lookup_spi_proto() does

current running CPU.\nThis is because that on load balance if the dst_cpu is not allowed by the\ntask, we'll re-select a new_dst_cpu as a candidate. If no task can be\nbalanced to dst_cpu we'll try to balance the task to the new_dst_cpu\ninstead. In this case when the migration disabled task is not on CPU it\nonly allows to run on its current CPU, load balance will select its\ncurrent CPU as new_dst_cpu and later triggers the warning above.\n\nThe new_dst_cpu is chosen from the env->dst_grpmask. Currently it\ncontains CPUs in sched_group_span() and if we have overlapped groups it's\npossible to run into this case. This patch makes env->dst_grpmask of\ngroup_balance_mask() which exclude any CPUs from the busiest group and\nsolve the issue. For balancing in a domain with no overlapped groups\nthe behaviour keeps same as before.", "title": "Vulnerability description" }, { "category": "general", "text": "The CVSS score(s) listed for this

'mdelay(10)' is added before calling 'padata_find_next' in the\n'padata_reorder' function, this issue could be reproduced easily with\nltp test (pcrypt_aead01).\nThis can be explained as bellow:\npcrypt_aead_encrypt\n...\npadata_do_parallel\nrefcount_inc(&pd->refcnt); // add refcnt\n...\npadata_do_serial\npadata_reorder // pd\nwhile (1) {\npadata_find_next(pd, true); // using

padata_find_next, UAF\n}\nIn the padata_reorder function, when it loops in 'while', if the alg is\ndeleted, the refcnt may be decreased to 0 before entering\n'padata_find_next', which leads to UAF.\nAs mentioned in [1], do_serial is supposed to be called with BHs disabled\nand always happen under RCU protection, to address this issue, add\nsynchronize_rcu() in 'padata_free_shell' wait for all _do_serial calls\nto finish.\n[1] https://lore.kernel.org/all/20221028160401.cccypv4euxikusiq@parnassus.localdomain/\n[2]

So VM_BUG_ON_PAGE(PagePoisoned(page)) is\ntriggered.

unpoison-pfn\n\n echo > /sys/kernel/debug/hwpoison/unpoison-pfn\n\nThis scenario can be identified by pfn_to_online_page() returning NULL. \nAnd ZONE_DEVICE pages are never expected, so we can simply

is unplugged.

Comparing ACPIID_LEN against a total string length doesn't\ntake into account the lengths of individual hid and uid buffers so the\ncheck is insufficient in some cases. For example if the length of hid\nstring is 4 and the length of the uid string is 260, the length of str\nwill be equal to ACPIID_LEN + 1 but uid string will overflow uid buffer\nwhich size is 256.\n\nThe same applies to the hid string with length 13 and uid string with\nlength 250.\n\nCheck the length of hid and uid strings separately to prevent\nbuffer overflow.\n\nFound by Linux

Thus, having a release callback for it is correct.\n\nAllocating the vm_dev struct with devres totally breaks this protection,\nthough. Instead of waiting for the vm_dev release callback, the memory\nis freed when the platform_device is removed. Resulting in a\nuse-after-free when finally the callback is to be called.\n\nTo easily see the problem, compile the kernel with\nCONFIG_DEBUG_KOBJECT_RELEASE and unbind with sysfs.\n\nThe fix is easy,

The ftrace_disable is set when an anomaly is\ndiscovered and to prevent any more damage, ftrace stops all text\nmodification. The issue that happened was that the ftrace_disable stops\nmore than just the text modification.\n\nWhen a module is loaded, its init functions can also be traced. Because\nkallsyms deletes the init functions after a module has loaded, ftrace\nsaves them when the module is loaded and function tracing is enabled. This\nallows the output of the function trace to show the init function names\ninstead of just their raw memory addresses.\n\nWhen a module is removed, ftrace_release_mod() is called, and if\nftrace_disable is set, it just returns without doing anything more. The\nproblem here is that it leaves the mod_list still around and if kallsyms\nis called, it will call into this code and access the module memory that\nhas already been freed as it will return:\n\n

add missing kref_get in handle_write_conflicts\n\nWith `two-primaries` enabled, DRBD tries to detect \"concurrent\" writes\nand handle write conflicts, so that even if you write to the same sector\nsimultaneously on both nodes, they end up with the identical data once\nthe writes are completed.\n\nIn handling \"superseeded\" writes, we forgot a kref_get,\nresulting in a premature drbd_destroy_device and use after free,\nand further to kernel crashes with symptoms.\n\nRelevance: No one should use DRBD as a random data generator, and apparently\nall users of \"two-primaries\" handle concurrent writes correctly on layer up.\nThat is cluster file systems use some distributed lock manager,\nand live migration in virtualization environments stops writes on one node\nbefore starting writes on the other node.\n\nWhich means that other than for \"test cases\",\nthis code path is never taken in real life.\n\nFYI, in DRBD 9, things are handled differently nowadays. We still detect\n\"write conflicts\", but no longer try to be smart about them.\nWe decided to disconnect hard instead: upper layers must not submit concurrent\nwrites.

the Linux kernel, the following vulnerability has been resolved:\n\nHID: asus: fix UAF via HID_CLAIMED_INPUT validation\n\nAfter hid_hw_start() is called hidinput_connect() will eventually be\ncalled to set up the device with the input layer since the\nHID_CONNECT_DEFAULT connect mask is used. During hidinput_connect()\nall input and output reports are processed and corresponding hid_inputs\nare allocated and configured via hidinput_configure_usages(). This\nprocess involves slot tagging report fields and configuring usages\nby setting relevant bits in the capability bitmaps. However it is possible\nthat the capability bitmaps are not set at all leading to the subsequent\nhidinput_has_been_populated() check to fail leading to the freeing of the\nhid_input and the underlying input device.\n\nThis becomes problematic because a malicious HID device like a\nASUS ROG N-Key keyboard can trigger the above scenario via a\nspecially crafted descriptor which then leads to a user-after-free\nwhen the name of the freed input device is written to later on after\nhid_hw_start(). Below, report 93 intentionally utilises the\nHID_UP_UNDEFINED Usage Page which is skipped during usage\nconfiguration, leading to the frees.\n\n0x05, 0x0D, // Usage Page (Digitizer)\n0x09, 0x05, //

the Linux kernel, the following vulnerability has been resolved:\n\ncnic: Fix use-after-free bugs in cnic_delete_task\n\nThe original code uses cancel_delayed_work() in cnic_cm_stop_bnx2x_hw(),\nwhich does not guarantee that the delayed work item 'delete_task' has\nfully completed if it was already running. Additionally, the delayed work\nitem is cyclic, the flush_workqueue() in cnic_cm_stop_bnx2x_hw() only\nblocks and waits for work items that were already queued to the\nworkqueue prior to its invocation. Any work items submitted after\nflush_workqueue() is called are not included in the set of tasks that the\nflush operation awaits. This means that after the cyclic work items have\nfinished executing, a delayed work item may still exist in the workqueue.\nThis leads to use-after-free scenarios where the cnic_dev is deallocated\nby cnic_free_dev(), while delete_task remains active and attempt to\ndereference cnic_dev in cnic_delete_task().\n\nA typical race condition is illustrated below:\n\nCPU 0 (cleanup) | CPU 1 (delayed work callback)\ncnic_netdev_event() |\n cnic_stop_hw() | cnic_delete_task()\n cnic_cm_stop_bnx2x_hw() | ...\n cancel_delayed_work() | /* the queue_delayed_work()\n flush_workqueue() | executes after flush_workqueue()*/\n | queue_delayed_work()\n cnic_free_dev(dev)//free | cnic_delete_task() //new instance\n | dev = cp->dev; //use\n\nReplace cancel_delayed_work() with cancel_delayed_work_sync() to ensure\nthat the cyclic delayed work item is properly canceled and that any\nongoing execution of the work item completes before the cnic_dev is\ndeallocated. Furthermore, since cancel_delayed_work_sync() uses\n__flush_work(work, true) to synchronously wait for any currently\nexecuting instance of the work item to finish, the flush_workqueue()\nbecomes redundant and should be removed.\n\nThis bug was identified through static analysis. To reproduce the issue\nand validate the fix, I simulated the cnic PCI device in QEMU and\nintroduced intentional delays — such as inserting calls to ssleep()\nwithin the cnic_delete_task() function — to increase the likelihood\nof triggering the bug.", "title": "Vulnerability description" }, { "category": "general", "text": "The CVSS score(s) listed for this vulnerability do not reflect the

the Linux kernel, the following vulnerability has been resolved:\n\nnilfs2: fix potential UAF of struct nilfs_sc_info in nilfs_segctor_thread()\n\nThe finalization of nilfs_segctor_thread() can race with\nnilfs_segctor_kill_thread() which terminates that thread, potentially\ncausing a use-after-free BUG as KASAN detected.\n\nAt the end of nilfs_segctor_thread(), it assigns NULL to \"sc_task\" member\nof \"struct nilfs_sc_info\" to indicate the thread has finished, and then\nnotifies nilfs_segctor_kill_thread() of this using waitqueue\n\"sc_wait_task\" on the struct nilfs_sc_info.\n\nHowever, here, immediately after the NULL assignment to \"sc_task\", it is\npossible that nilfs_segctor_kill_thread() will detect it and return to\ncontinue the deallocation, freeing the nilfs_sc_info structure before the\nthread does the notification.\n\nThis fixes the issue by protecting the NULL assignment to \"sc_task\" and\nits notification, with spinlock \"sc_state_lock\" of the struct\nnilfs_sc_info. Since nilfs_segctor_kill_thread() does a final check to\nsee if \"sc_task\" is NULL with \"sc_state_lock\" locked, this can eliminate\nthe race.", "title": "Vulnerability description" }, { "category":

resolved:\n\natm: clip: Fix infinite recursive call of clip_push().\n\nsyzbot reported the splat below. [0]\n\nThis happens if we call ioctl(ATMARP_MKIP) more than once.\n\nDuring the first call, clip_mkip() sets clip_push() to vcc->push(),\nand the second call copies it to clip_vcc->old_push().\n\nLater, when the socket is close()d, vcc_destroy_socket() passes\nNULL skb to clip_push(), which calls clip_vcc->old_push(),\ntriggering the infinite recursion.\n\nLet's prevent the second ioctl(ATMARP_MKIP) by checking\nvcc->user_back, which is allocated by the first call as clip_vcc.\n\nNote also that we use lock_sock() to prevent racy calls.\n\n[0]:\nBUG: TASK

brcmfmac: fix use-after-free when rescheduling brcmf_btcoex_info work\n\nThe brcmf_btcoex_detach() only shuts down the btcoex timer, if the\nflag timer_on is false. However, the brcmf_btcoex_timerfunc(), which\nruns as timer handler, sets timer_on to false. This creates critical\nrace conditions:\n\n1.If brcmf_btcoex_detach() is called while brcmf_btcoex_timerfunc()\nis executing, it may observe timer_on as false and skip the call to\ntimer_shutdown_sync().\n\n2.The brcmf_btcoex_timerfunc() may then reschedule the brcmf_btcoex_info\nworker after the cancel_work_sync() has been executed, resulting in\nuse-after-free bugs.\n\nThe use-after-free bugs occur in two distinct scenarios, depending on\nthe timing of when the brcmf_btcoex_info struct is freed relative to\nthe execution of its worker thread.\n\nScenario 1: Freed before the worker is scheduled\n\nThe brcmf_btcoex_info is deallocated before the worker is scheduled.\nA race condition can occur when schedule_work(&bt_local->work) is\ncalled after the target memory has been freed. The sequence of events\nis detailed below:\n\nCPU0 | CPU1\nbrcmf_btcoex_detach | brcmf_btcoex_timerfunc\n | bt_local->timer_on = false;\n if (cfg->btcoex->timer_on) |\n ... |\n cancel_work_sync(); |\n ... |\n kfree(cfg->btcoex); // FREE |\n | schedule_work(&bt_local->work); // USE\n\nScenario 2: Freed after the worker is scheduled\n\nThe brcmf_btcoex_info is freed after the worker has been scheduled\nbut before or during its execution. In this case, statements within\nthe brcmf_btcoex_handler() — such as the container_of macro and\nsubsequent dereferences of the brcmf_btcoex_info object will cause\na use-after-free access. The following timeline illustrates this\nscenario:\n\nCPU0 | CPU1\nbrcmf_btcoex_detach | brcmf_btcoex_timerfunc\n | bt_local->timer_on = false;\n if (cfg->btcoex->timer_on) |\n ... |\n cancel_work_sync(); |\n ... | schedule_work(); // Reschedule\n |\n kfree(cfg->btcoex); // FREE | brcmf_btcoex_handler() // Worker\n /* | btci = container_of(....); // USE\n The kfree() above could | ...\n also occur at any point | btci-> // USE\n during the worker's execution|\n */ |\n\nTo resolve the race conditions, drop the conditional check and call\ntimer_shutdown_sync() directly. It can deactivate the timer reliably,\nregardless of its current state. Once stopped, the timer_on state is\nthen set to false.", "title": "Vulnerability description" }, { "category": "general", "text": "The CVSS score(s) listed for this vulnerability do not reflect the

__atm_dev_lookup()\niterates over.\n\nSo, there will be a small race window where the device does not exist on\nthe device list but procfs/sysfs are still not removed, triggering the\nsplat.\n\nLet's hold the mutex until procfs/sysfs are removed in\natm_dev_deregister().\n\n[0]:\nproc_dir_entry 'atm/atmtcp:0' already registered\nWARNING: CPU: 0 PID: 5919 at fs/proc/generic.c:377

fix use-after-free of nilfs_root in dirtying inodes via iput\n\nDuring unmount process of nilfs2, nothing holds nilfs_root structure after\nnilfs2 detaches its writer in nilfs_detach_log_writer(). Previously,\nnilfs_evict_inode() could cause use-after-free read for nilfs_root if\ninodes are left in \"garbage_list\" and released by nilfs_dispose_list at\nthe end of nilfs_detach_log_writer(), and this bug was fixed by commit\n9b5a04ac3ad9 (\"nilfs2: fix use-after-free bug of nilfs_root in\nnilfs_evict_inode()\").\n\nHowever, it turned out that there is another possibility of UAF in the\ncall path where mark_inode_dirty_sync() is called from iput():\n\nnilfs_detach_log_writer()\n nilfs_dispose_list()\n iput()\n mark_inode_dirty_sync()\n __mark_inode_dirty()\n nilfs_dirty_inode()\n __nilfs_mark_inode_dirty()\n nilfs_load_inode_block() --> causes UAF of nilfs_root struct\n\nThis can happen after commit 0ae45f63d4ef (\"vfs: add support for a\nlazytime mount option\"), which changed iput() to call\nmark_inode_dirty_sync() on its final reference if i_state has I_DIRTY_TIME\nflag and i_nlink is non-zero.\n\nThis issue appears after commit 28a65b49eb53 (\"nilfs2: do not write dirty\ndata after degenerating to read-only\") when using the syzbot reproducer,\nbut the issue has potentially existed before.\n\nFix this issue by adding a \"purging flag\" to the nilfs structure, setting\nthat flag while disposing the \"garbage_list\" and checking it in\n__nilfs_mark_inode_dirty().\n\nUnlike commit 9b5a04ac3ad9 (\"nilfs2: fix use-after-free bug of nilfs_root\nin nilfs_evict_inode()\"), this patch does not rely on ns_writer to\ndetermine whether to skip operations, so as not to break recovery on\nmount. The nilfs_salvage_orphan_logs routine dirties the buffer of\nsalvaged data before attaching the log writer, so changing\n__nilfs_mark_inode_dirty() to skip the operation when ns_writer is NULL\nwill cause recovery write to fail.

the Linux kernel, the following vulnerability has been resolved:\n\nBluetooth: hci_core: Fix use-after-free in vhci_flush()\n\nsyzbot reported use-after-free in vhci_flush() without repro. [0]\n\nFrom the splat, a thread close()d a vhci file descriptor while\nits device was being used by iotcl() on another thread.\n\nOnce the last fd refcnt is released, vhci_release() calls\nhci_unregister_dev(), hci_free_dev(), and kfree() for struct\nvhci_data, which is set to hci_dev->dev->driver_data.\n\nThe problem is that there is no synchronisation after unlinking\nhdev from hci_dev_list in hci_unregister_dev(). There might be\nanother thread still accessing the hdev which was fetched before\nthe unlink operation.\n\nWe can use SRCU for such synchronisation.\n\nLet's run hci_dev_reset() under SRCU and wait for its completion\nin hci_unregister_dev().\n\nAnother option would be to restore hci_dev->destruct(), which was\nremoved in commit 587ae086f6e4 (\"Bluetooth: Remove unused\nhci-destruct cb\"). However, this would not be a good solution, as\nwe should not run hci_unregister_dev() while there are in-flight\nioctl() requests, which could lead to another data-race KCSAN splat.\n\nNote that other drivers seem to have the same problem, for exmaple,\nvirtbt_remove().\n\n[0]:\nBUG: KASAN: slab-use-after-free in skb_queue_empty_lockless include/linux/skbuff.h:1891 [inline]\nBUG: KASAN:

"CVE-2025-22083", "cwe": { "id": "CWE-416", "name": "Use After Free" }, "notes": [ { "category": "description", "text": "In the Linux kernel, the following vulnerability has been resolved:\n\nvhost-scsi: Fix handling of multiple calls to vhost_scsi_set_endpoint\n\nIf vhost_scsi_set_endpoint is called multiple times without a\nvhost_scsi_clear_endpoint between them, we can hit multiple bugs\nfound by Haoran Zhang:\n\n1. Use-after-free when no tpgs are found:\n\nThis fixes a use after free that occurs when vhost_scsi_set_endpoint is\ncalled more than once and calls after the first call do not find any\ntpgs to add to the vs_tpg. When vhost_scsi_set_endpoint first finds\ntpgs to add to the vs_tpg array match=true, so we will do:\n\nvhost_vq_set_backend(vq, vs_tpg);\n...\n\nkfree(vs->vs_tpg);\nvs->vs_tpg = vs_tpg;\n\nIf vhost_scsi_set_endpoint is called again and no tpgs are found\nmatch=false so we skip the vhost_vq_set_backend call leaving the\npointer to the vs_tpg we then free via:\n\nkfree(vs->vs_tpg);\nvs->vs_tpg = vs_tpg;\n\nIf a scsi request is then sent we do:\n\nvhost_scsi_handle_vq -> vhost_scsi_get_req -> vhost_vq_get_backend\n\nwhich sees the vs_tpg we just did a kfree on.\n\n2. Tpg dir removal hang:\n\nThis patch fixes an issue where we cannot remove a LIO/target layer\ntpg (and structs above it like the target) dir due to the refcount\ndropping to -1.\n\nThe problem is that if vhost_scsi_set_endpoint detects a tpg is already\nin the vs->vs_tpg array or if the tpg has been removed so\ntarget_depend_item fails, the undepend goto handler will do\ntarget_undepend_item on all tpgs in the vs_tpg array dropping their\nrefcount to 0. At this time vs_tpg contains both the tpgs we have added\nin the current vhost_scsi_set_endpoint call as well as tpgs we added in\nprevious calls which are also in vs->vs_tpg.\n\nLater, when vhost_scsi_clear_endpoint runs it will do\ntarget_undepend_item on all the tpgs in the vs->vs_tpg which will drop\ntheir refcount to -1. Userspace will then not be able to remove the tpg\nand will hang when it tries to do rmdir on the tpg dir.\n\n3. Tpg leak:\n\nThis fixes a bug where we can leak tpgs and cause them to be\nun-removable because the target name is overwritten when\nvhost_scsi_set_endpoint is called multiple times but with different\ntarget names.\n\nThe bug occurs if a user has called VHOST_SCSI_SET_ENDPOINT and setup\na vhost-scsi device to target/tpg mapping, then calls\nVHOST_SCSI_SET_ENDPOINT again with a new target name that has tpgs we\nhaven't seen before (target1 has tpg1 but target2 has tpg2). When this\nhappens we don't teardown the old target tpg mapping and just overwrite\nthe target name and the vs->vs_tpg array. Later when we do\nvhost_scsi_clear_endpoint, we are passed in either target1 or target2's\nname and we will only match that target's tpgs when we loop over the\nvs->vs_tpg. We will then return from the function without doing\ntarget_undepend_item on the tpgs.\n\nBecause of all these bugs, it looks like being able to call\nvhost_scsi_set_endpoint multiple times was never supported. The major\nuser, QEMU, already has checks to prevent this use case. So to fix the\nissues, this patch prevents vhost_scsi_set_endpoint from being called\nif it's already successfully added tpgs. To add, remove or change the\ntpg config or target name, you must do a vhost_scsi_clear_endpoint\nfirst.", "title": "Vulnerability description" }, { "category": "general", "text": "The CVSS score(s)

offset[0] and level should zero.\n\nThe possible case should be in f2fs_do_truncate_blocks(), we try to\ntruncate inode size to zero, however, dn.ofs_in_node is zero and\ndn.node_page is not an inode page, so it fails to truncate inode page,\nand then pass zeroed free_from to f2fs_truncate_inode_blocks(), result\nin this issue.\n\n\tif (dn.ofs_in_node || IS_INODE(dn.node_page))
