"text": "In the Linux kernel, the following vulnerability has been resolved:\n\nnet/mlx5e: Fix deadlock in tc route query code\n\nCited commit causes ABBA deadlock[0] when peer flows are created while\nholding the devcom rw semaphore. Due to peer flows offload implementation\nthe lock is taken much higher up the call chain and there is no obvious way\nto easily fix the deadlock. Instead, since tc route query code needs the\npeer eswitch structure only to perform a lookup in xarray and doesn't\nperform any sleeping operations with it, refactor the code for lockless\nexecution in following ways:\n\n- RCUify the devcom 'data' pointer. When resetting the pointer\nsynchronously wait for RCU grace period before returning. This is fine\nsince devcom is currently only used for synchronization of\npairing/unpairing of eswitches which is rare and already expensive as-is.\n\n- Wrap all usages of 'paired' boolean in {READ|WRITE}_ONCE(). The flag has\nalready been used in some unlocked contexts without proper\nannotations (e.g. users of mlx5_devcom_is_paired() function), but it wasn't\nan issue since all relevant code paths checked it again after obtaining the\ndevcom semaphore. Now it is also used by mlx5_devcom_get_peer_data_rcu() as\n\"best effort\" check to return NULL when devcom is being unpaired. Note that\nwhile RCU read lock doesn't prevent the unpaired flag from being changed\nconcurrently it still guarantees that reader can continue to use 'data'.\n\n- Refactor mlx5e_tc_query_route_vport() function to use new\nmlx5_devcom_get_peer_data_rcu() API which fixes the deadlock.\n\n[0]:\n\n[ 164.599612] ======================================================\n[ 164.600142] WARNING: possible circular locking dependency detected\n[ 164.600667] 6.3.0-rc3+ #1 Not tainted\n[ 164.601021] ------------------------------------------------------\n[ 164.601557] handler1/3456 is trying to acquire lock:\n[ 164.601998] ffff88811f1714b0 (&esw->offloads.encap_tbl_lock){+.+.}-{3:3}, at: mlx5e_attach_encap+0xd8/0x8b0 [mlx5_core]\n[ 164.603078]\n but task is already holding lock:\n[ 164.603617] ffff88810137fc98 (&comp->sem){++++}-{3:3}, at: mlx5_devcom_get_peer_data+0x37/0x80 [mlx5_core]\n[ 164.604459]\n which lock already depends on the new lock.\n\n[ 164.605190]\n the existing dependency chain (in reverse order) is:\n[ 164.605848]\n -> #1 (&comp->sem){++++}-{3:3}:\n[ 164.606380] down_read+0x39/0x50\n[ 164.606772] mlx5_devcom_get_peer_data+0x37/0x80 [mlx5_core]\n[ 164.607336] mlx5e_tc_query_route_vport+0x86/0xc0 [mlx5_core]\n[ 164.607914] mlx5e_tc_tun_route_lookup+0x1a4/0x1d0 [mlx5_core]\n[ 164.608495] mlx5e_attach_decap_route+0xc6/0x1e0 [mlx5_core]\n[ 164.609063] mlx5e_tc_add_fdb_flow+0x1ea/0x360 [mlx5_core]\n[ 164.609627] __mlx5e_add_fdb_flow+0x2d2/0x430 [mlx5_core]\n[ 164.610175] mlx5e_configure_flower+0x952/0x1a20 [mlx5_core]\n[ 164.610741] tc_setup_cb_add+0xd4/0x200\n[ 164.611146] fl_hw_replace_filter+0x14c/0x1f0 [cls_flower]\n[ 164.611661] fl_change+0xc95/0x18a0 [cls_flower]\n[ 164.612116] tc_new_tfilter+0x3fc/0xd20\n[ 164.612516] rtnetlink_rcv_msg+0x418/0x5b0\n[ 164.612936] netlink_rcv_skb+0x54/0x100\n[ 164.613339] netlink_unicast+0x190/0x250\n[ 164.613746] netlink_sendmsg+0x245/0x4a0\n[ 164.614150] sock_sendmsg+0x38/0x60\n[ 164.614522] ____sys_sendmsg+0x1d0/0x1e0\n[ 164.614934] ___sys_sendmsg+0x80/0xc0\n[ 164.615320] __sys_sendmsg+0x51/0x90\n[ 164.615701] do_syscall_64+0x3d/0x90\n[ 164.616083] entry_SYSCALL_64_after_hwframe+0x46/0xb0\n[ 164.616568]\n -> #0 (&esw->offloads.encap_tbl_lock){+.+.}-{3:3}:\n[ 164.617210] __lock_acquire+0x159e/0x26e0\n[ 164.617638] lock_acquire+0xc2/0x2a0\n[ 164.618018] __mutex_lock+0x92/0xcd0\n[ 164.618401] mlx5e_attach_encap+0xd8/0x8b0 [mlx5_core]\n[ 164.618943] post_process_attr+0x153/0x2d0 [\n---truncated---",

"text": "In the Linux kernel, the following vulnerability has been 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 a truly global search - across all states,\nregardless of hash bucket and matches SPI and proto.",

"text": "In the Linux kernel, the following vulnerability has been resolved:\n\nmptcp: pm: avoid possible UaF when selecting endp\n\nselect_local_address() and select_signal_address() both select an\nendpoint entry from the list inside an RCU protected section, but return\na reference to it, to be read later on. If the entry is dereferenced\nafter the RCU unlock, reading info could cause a Use-after-Free.\n\nA simple solution is to copy the required info while inside the RCU\nprotected section to avoid any risk of UaF later. The address ID might\nneed to be modified later to handle the ID0 case later, so a copy seems\nOK to deal with.",

"text": "In the Linux kernel, the following vulnerability has been resolved:\n\nkernfs: Fix UAF in polling when open file is released\n\nA use-after-free (UAF) vulnerability was identified in the PSI (Pressure\nStall Information) monitoring mechanism:\n\nBUG: KASAN: slab-use-after-free in psi_trigger_poll+0x3c/0x140\nRead of size 8 at addr ffff3de3d50bd308 by task systemd/1\n\npsi_trigger_poll+0x3c/0x140\ncgroup_pressure_poll+0x70/0xa0\ncgroup_file_poll+0x8c/0x100\nkernfs_fop_poll+0x11c/0x1c0\nep_item_poll.isra.0+0x188/0x2c0\n\nAllocated by task 1:\ncgroup_file_open+0x88/0x388\nkernfs_fop_open+0x73c/0xaf0\ndo_dentry_open+0x5fc/0x1200\nvfs_open+0xa0/0x3f0\ndo_open+0x7e8/0xd08\npath_openat+0x2fc/0x6b0\ndo_filp_open+0x174/0x368\n\nFreed by task 8462:\ncgroup_file_release+0x130/0x1f8\nkernfs_drain_open_files+0x17c/0x440\nkernfs_drain+0x2dc/0x360\nkernfs_show+0x1b8/0x288\ncgroup_file_show+0x150/0x268\ncgroup_pressure_write+0x1dc/0x340\ncgroup_file_write+0x274/0x548\n\nReproduction Steps:\n1. Open test/cpu.pressure and establish epoll monitoring\n2. Disable monitoring: echo 0 > test/cgroup.pressure\n3. Re-enable monitoring: echo 1 > test/cgroup.pressure\n\nThe race condition occurs because:\n1. When cgroup.pressure is disabled (echo 0 > cgroup.pressure), it:\n - Releases PSI triggers via cgroup_file_release()\n - Frees of->priv through kernfs_drain_open_files()\n2. While epoll still holds reference to the file and continues polling\n3. Re-enabling (echo 1 > cgroup.pressure) accesses freed of->priv\n\nepolling\t\t\tdisable/enable cgroup.pressure\nfd=open(cpu.pressure)\nwhile(1)\n...\nepoll_wait\nkernfs_fop_poll\nkernfs_get_active = true\techo 0 > cgroup.pressure\n...\t\t\t\tcgroup_file_show\n\t\t\t\tkernfs_show\n\t\t\t\t// inactive kn\n\t\t\t\tkernfs_drain_open_files\n\t\t\t\tcft->release(of);\n\t\t\t\tkfree(ctx);\n\t\t\t\t...\nkernfs_get_active = false\n\t\t\t\techo 1 > cgroup.pressure\n\t\t\t\tkernfs_show\n\t\t\t\tkernfs_activate_one(kn);\nkernfs_fop_poll\nkernfs_get_active = true\ncgroup_file_poll\npsi_trigger_poll\n// UAF\n...\nend: close(fd)\n\nTo address this issue, introduce kernfs_get_active_of() for kernfs open\nfiles to obtain active references. This function will fail if the open file\nhas been released. Replace kernfs_get_active() with kernfs_get_active_of()\nto prevent further operations on released file descriptors.",

The variable 'dma_len' in the URB packet\ncould be manipulated, which could trigger an integer underflow of\n'seg_len' in 'mt7601u_rx_process_seg()'. This underflow subsequently\ncauses the 'bad_frame' checks in 'mt7601u_rx_skb_from_seg()' to be\nbypassed, eventually leading to a dereference of the pointer 'p', which\nis a null pointer.\n\nEnsure that 'dma_len' is greater than 'min_seg_len'.\n\nFound by a modified version of syzkaller.\n\nKASAN: null-ptr-deref in range [0x0000000000000008-0x000000000000000f]\nCPU: 0 PID: 12 Comm: ksoftirqd/0 Tainted: G W O 5.14.0+\n#139\nHardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS\nrel-1.12.1-0-ga5cab58e9a3f-prebuilt.qemu.org 04/01/2014\nRIP: 0010:skb_add_rx_frag+0x143/0x370\nCode: e2 07 83 c2 03 38 ca 7c 08 84 c9 0f 85 86 01 00 00 4c 8d 7d 08 44\n89 68 08 48 b8 00 00 00 00 00 fc ff df 4c 89 fa 48 c1 ea 03 <80> 3c 02\n00 0f 85 cd 01 00 00 48 8b 45 08 a8 01 0f 85 3d 01 00 00\nRSP: 0018:ffffc900000cfc90 EFLAGS: 00010202\nRAX: dffffc0000000000 RBX: ffff888115520dc0 RCX: 0000000000000000\nRDX: 0000000000000001 RSI: ffff8881118430c0 RDI: ffff8881118430f8\nRBP: 0000000000000000 R08: 0000000000000e09 R09: 0000000000000010\nR10: ffff888111843017 R11: ffffed1022308602 R12: 0000000000000000\nR13: 0000000000000e09 R14: 0000000000000010 R15: 0000000000000008\nFS: 0000000000000000(0000) GS:ffff88811a800000(0000)\nknlGS:0000000000000000\nCS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033\nCR2: 000000004035af40 CR3: 00000001157f2000 CR4: 0000000000750ef0\nDR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000\nDR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400\nPKRU: 55555554\nCall Trace:\n mt7601u_rx_tasklet+0xc73/0x1270\n ? mt7601u_submit_rx_buf.isra.0+0x510/0x510\n ? tasklet_action_common.isra.0+0x79/0x2f0\n tasklet_action_common.isra.0+0x206/0x2f0\n __do_softirq+0x1b5/0x880\n ? tasklet_unlock+0x30/0x30\n run_ksoftirqd+0x26/0x50\n smpboot_thread_fn+0x34f/0x7d0\n ? smpboot_register_percpu_thread+0x370/0x370\n kthread+0x3a1/0x480\n ? set_kthread_struct+0x120/0x120\n ret_from_fork+0x1f/0x30\nModules linked in: 88XXau(O) 88x2bu(O)\n---[ end trace 57f34f93b4da0f9b ]---\nRIP: 0010:skb_add_rx_frag+0x143/0x370\nCode: e2 07 83 c2 03 38 ca 7c 08 84 c9 0f 85 86 01 00 00 4c 8d 7d 08 44\n89 68 08 48 b8 00 00 00 00 00 fc ff df 4c 89 fa 48 c1 ea 03 <80> 3c 02\n00 0f 85 cd 01 00 00 48 8b 45 08 a8 01 0f 85 3d 01 00 00\nRSP: 0018:ffffc900000cfc90 EFLAGS: 00010202\nRAX: dffffc0000000000 RBX: ffff888115520dc0 RCX: 0000000000000000\nRDX: 0000000000000001 RSI: ffff8881118430c0 RDI: ffff8881118430f8\nRBP: 0000000000000000 R08: 0000000000000e09 R09: 0000000000000010\nR10: ffff888111843017 R11: ffffed1022308602 R12: 0000000000000000\nR13: 0000000000000e09 R14: 0000000000000010 R15: 0000000000000008\nFS: 0000000000000000(0000) GS:ffff88811a800000(0000)\nknlGS:0000000000000000\nCS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033\nCR2: 000000004035af40 CR3: 00000001157f2000 CR4: 0000000000750ef0\nDR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000\nDR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400\nPKRU: 55555554",

"text": "In the Linux kernel, the following vulnerability has been resolved:\nnfsd: release svc_expkey/svc_export with rcu_work\nThe last reference for `cache_head` can be reduced to zero in `c_show`\nand `e_show`(using `rcu_read_lock` and `rcu_read_unlock`). Consequently,\n`svc_export_put` and `expkey_put` will be invoked, leading to two\nissues:\n1. The `svc_export_put` will directly free ex_uuid. However,\n`e_show`/`c_show` will access `ex_uuid` after `cache_put`, which can\ntrigger a use-after-free issue, shown below.\n==================================================================\nBUG: KASAN: slab-use-after-free in svc_export_show+0x362/0x430 [nfsd]\nRead of size 1 at addr ff11000010fdc120 by task cat/870\nCPU: 1 UID: 0 PID: 870 Comm: cat Not tainted 6.12.0-rc3+ #1\nHardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS\n1.16.1-2.fc37 04/01/2014\nCall Trace:\n\ndump_stack_lvl+0x53/0x70\nprint_address_description.constprop.0+0x2c/0x3a0\nprint_report+0xb9/0x280\nkasan_report+0xae/0xe0\nsvc_export_show+0x362/0x430 [nfsd]\nc_show+0x161/0x390 [sunrpc]\nseq_read_iter+0x589/0x770\nseq_read+0x1e5/0x270\nproc_reg_read+0xe1/0x140\nvfs_read+0x125/0x530\nksys_read+0xc1/0x160\ndo_syscall_64+0x5f/0x170\nentry_SYSCALL_64_after_hwframe+0x76/0x7e\nAllocated by task 830:\nkasan_save_stack+0x20/0x40\nkasan_save_track+0x14/0x30\n__kasan_kmalloc+0x8f/0xa0\n__kmalloc_node_track_caller_noprof+0x1bc/0x400\nkmemdup_noprof+0x22/0x50\nsvc_export_parse+0x8a9/0xb80 [nfsd]\ncache_do_downcall+0x71/0xa0 [sunrpc]\ncache_write_procfs+0x8e/0xd0 [sunrpc]\nproc_reg_write+0xe1/0x140\nvfs_write+0x1a5/0x6d0\nksys_write+0xc1/0x160\ndo_syscall_64+0x5f/0x170\nentry_SYSCALL_64_after_hwframe+0x76/0x7e\nFreed by task 868:\nkasan_save_stack+0x20/0x40\nkasan_save_track+0x14/0x30\nkasan_save_free_info+0x3b/0x60\n__kasan_slab_free+0x37/0x50\nkfree+0xf3/0x3e0\nsvc_export_put+0x87/0xb0 [nfsd]\ncache_purge+0x17f/0x1f0 [sunrpc]\nnfsd_destroy_serv+0x226/0x2d0 [nfsd]\nnfsd_svc+0x125/0x1e0 [nfsd]\nwrite_threads+0x16a/0x2a0 [nfsd]\nnfsctl_transaction_write+0x74/0xa0 [nfsd]\nvfs_write+0x1a5/0x6d0\nksys_write+0xc1/0x160\ndo_syscall_64+0x5f/0x170\nentry_SYSCALL_64_after_hwframe+0x76/0x7e\n2.

"text": "In the Linux kernel, the following vulnerability has been resolved:\n\nusb: xhci: Apply the link chain quirk on NEC isoc endpoints\n\nTwo clearly different specimens of NEC uPD720200 (one with start/stop\nbug, one without) were seen to cause IOMMU faults after some Missed\nService Errors. Faulting address is immediately after a transfer ring\nsegment and patched dynamic debug messages revealed that the MSE was\nreceived when waiting for a TD near the end of that segment:\n\n[ 1.041954] xhci_hcd: Miss service interval error for slot 1 ep 2 expected TD DMA ffa08fe0\n[ 1.042120] xhci_hcd: AMD-Vi: Event logged [IO_PAGE_FAULT domain=0x0005 address=0xffa09000 flags=0x0000]\n[ 1.042146] xhci_hcd: AMD-Vi: Event logged [IO_PAGE_FAULT domain=0x0005 address=0xffa09040 flags=0x0000]\n\nIt gets even funnier if the next page is a ring segment accessible to\nthe HC. Below, it reports MSE in segment at ff1e8000, plows through a\nzero-filled page at ff1e9000 and starts reporting events for TRBs in\npage at ff1ea000 every microframe, instead of jumping to seg ff1e6000.\n\n[ 7.041671] xhci_hcd: Miss service interval error for slot 1 ep 2 expected TD DMA ff1e8fe0\n[ 7.041999] xhci_hcd: Miss service interval error for slot 1 ep 2 expected TD DMA ff1e8fe0\n[ 7.042011] xhci_hcd: WARN: buffer overrun event for slot 1 ep 2 on endpoint\n[ 7.042028] xhci_hcd: All TDs skipped for slot 1 ep 2.

Was it\ncaused by the above? I don't know, but it may have been. The disk\nwas working without any other issues and generated PCIe traffic to\nstarve the NEC of upstream BW and trigger those MSEs. The two HCs\nshared one x1 slot by means of a commercial \"PCIe splitter\" board.\n\n[ 7.162604] usb 10-2: reset SuperSpeed USB device number 3 using xhci_hcd\n[ 7.178990] sd 9:0:0:0: [sdb] tag#0 UNKNOWN(0x2003) Result: hostbyte=0x07 driverbyte=DRIVER_OK cmd_age=0s\n[ 7.179001] sd 9:0:0:0: [sdb] tag#0 CDB: opcode=0x28 28 00 04 02 ae 00 00 02 00 00\n[ 7.179004] I/O error, dev sdb, sector 67284480 op 0x0:(READ) flags 0x80700 phys_seg 5 prio class 0\n\nFortunately, it appears that this ridiculous bug is avoided by setting\nthe chain bit of Link TRBs on isochronous rings. Other ancient HCs are\nknown which also expect the bit to be set and they ignore Link TRBs if\nit's not. Reportedly, 0.95 spec guaranteed that the bit is set.\n\nThe bandwidth-starved NEC HC running a 32KB/uframe UVC endpoint reports\ntens of MSEs per second and runs into the bug within seconds. Chaining\nLink TRBs allows the same workload to run for many minutes, many times.\n\nNo ne\n---truncated---",

"text": "In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: rtlwifi: Fix global-out-of-bounds bug in _rtl8812ae_phy_set_txpower_limit()\n\nThere is a global-out-of-bounds reported by KASAN:\n\n BUG: KASAN: global-out-of-bounds in\n _rtl8812ae_eq_n_byte.part.0+0x3d/0x84 [rtl8821ae]\n Read of size 1 at addr ffffffffa0773c43 by task NetworkManager/411\n\n CPU: 6 PID: 411 Comm: NetworkManager Tainted: G D\n 6.1.0-rc8+ #144 e15588508517267d37\n Hardware name: QEMU Standard PC (Q35 + ICH9, 2009),\n Call Trace:\n \n ...\n kasan_report+0xbb/0x1c0\n _rtl8812ae_eq_n_byte.part.0+0x3d/0x84 [rtl8821ae]\n rtl8821ae_phy_bb_config.cold+0x346/0x641 [rtl8821ae]\n rtl8821ae_hw_init+0x1f5e/0x79b0 [rtl8821ae]\n ...\n \n\nThe root cause of the problem is that the comparison order of\n\"prate_section\" in _rtl8812ae_phy_set_txpower_limit() is wrong. The\n_rtl8812ae_eq_n_byte() is used to compare the first n bytes of the two\nstrings from tail to head, which causes the problem. In the\n_rtl8812ae_phy_set_txpower_limit(), it was originally intended to meet\nthis requirement by carefully designing the comparison order.\nFor example, \"pregulation\" and \"pbandwidth\" are compared in order of\nlength from small to large, first is 3 and last is 4. However, the\ncomparison order of \"prate_section\" dose not obey such order requirement,\ntherefore when \"prate_section\" is \"HT\", when comparing from tail to head,\nit will lead to access out of bounds in _rtl8812ae_eq_n_byte(). As\nmentioned above, the _rtl8812ae_eq_n_byte() has the same function as\nstrcmp(), so just strcmp() is enough.\n\nFix it by removing _rtl8812ae_eq_n_byte() and use strcmp() barely.\nAlthough it can be fixed by adjusting the comparison order of\n\"prate_section\", this may cause the value of \"rate_section\" to not be\nfrom 0 to 5. In addition, commit \"21e4b0726dc6\" not only moved driver\nfrom staging to regular tree, but also added setting txpower limit\nfunction during the driver config phase, so the problem was introduced\nby this commit.",

It's easy to repro with YNL:\n$ ./cli.py --spec netlink/specs/ovs_datapath.yaml \\\n--do new \\\n--json '{\"upcall-pid\": 1, \"name\":\"my-dp\"}'\n$ ./cli.py --spec netlink/specs/ovs_vport.yaml \\\n--do new \\\n--json '{\"upcall-pid\": \"00000001\", \"name\": \"some-port0\", \"dp-ifindex\":3,\"ifindex\":4294901760,\"type\":2}'\n$ ip link show\n-65536: some-port0: mtu 1500 qdisc noop state DOWN mode DEFAULT group default qlen 1000\nlink/ether 7a:48:21:ad:0b:fb brd ff:ff:ff:ff:ff:ff\n...\nValidate the inputs.

If we fail to\nallocate that clone, proceeding with async decryption can lead to\nvarious issues (UAF on the skb, writing into userspace memory after\nthe recv() call has returned).\nIn this case, wait for all pending decryption requests.",

"text": "In the Linux kernel, the following vulnerability has been resolved:\n\nvxlan: Fix nexthop hash size\n\nThe nexthop code expects a 31 bit hash, such as what is returned by\nfib_multipath_hash() and rt6_multipath_hash(). Passing the 32 bit hash\nreturned by skb_get_hash() can lead to problems related to the fact that\n'int hash' is a negative number when the MSB is set.\n\nIn the case of hash threshold nexthop groups, nexthop_select_path_hthr()\nwill disproportionately select the first nexthop group entry. In the case\nof resilient nexthop groups, nexthop_select_path_res() may do an out of\nbounds access in nh_buckets[], for example:\n hash = -912054133\n num_nh_buckets = 2\n bucket_index = 65535\n\nwhich leads to the following panic:\n\nBUG: unable to handle page fault for address: ffffc900025910c8\nPGD 100000067 P4D 100000067 PUD 10026b067 PMD 0\nOops: 0002 [#1] PREEMPT SMP KASAN NOPTI\nCPU: 4 PID: 856 Comm: kworker/4:3 Not tainted 6.5.0-rc2+ #34\nHardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.16.2-debian-1.16.2-1 04/01/2014\nWorkqueue: ipv6_addrconf addrconf_dad_work\nRIP: 0010:nexthop_select_path+0x197/0xbf0\nCode: c1 e4 05 be 08 00 00 00 4c 8b 35 a4 14 7e 01 4e 8d 6c 25 00 4a 8d 7c 25 08 48 01 dd e8 c2 25 15 ff 49 8d 7d 08 e8 39 13 15 ff <4d> 89 75 08 48 89 ef e8 7d 12 15 ff 48 8b 5d 00 e8 14 55 2f 00 85\nRSP: 0018:ffff88810c36f260 EFLAGS: 00010246\nRAX: 0000000000000000 RBX: 00000000002000c0 RCX: ffffffffaf02dd77\nRDX: dffffc0000000000 RSI: 0000000000000008 RDI: ffffc900025910c8\nRBP: ffffc900025910c0 R08: 0000000000000001 R09: fffff520004b2219\nR10: ffffc900025910cf R11: 31392d2068736168 R12: 00000000002000c0\nR13: ffffc900025910c0 R14: 00000000fffef608 R15: ffff88811840e900\nFS: 0000000000000000(0000) GS:ffff8881f7000000(0000) knlGS:0000000000000000\nCS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033\nCR2: ffffc900025910c8 CR3: 0000000129d00000 CR4: 0000000000750ee0\nPKRU: 55555554\nCall Trace:\n \n ? __die+0x23/0x70\n ? page_fault_oops+0x1ee/0x5c0\n ? __pfx_is_prefetch.constprop.0+0x10/0x10\n ? __pfx_page_fault_oops+0x10/0x10\n ? search_bpf_extables+0xfe/0x1c0\n ? fixup_exception+0x3b/0x470\n ? exc_page_fault+0xf6/0x110\n ? asm_exc_page_fault+0x26/0x30\n ? nexthop_select_path+0x197/0xbf0\n ? nexthop_select_path+0x197/0xbf0\n ? lock_is_held_type+0xe7/0x140\n vxlan_xmit+0x5b2/0x2340\n ? __lock_acquire+0x92b/0x3370\n ? __pfx_vxlan_xmit+0x10/0x10\n ? __pfx___lock_acquire+0x10/0x10\n ? __pfx_register_lock_class+0x10/0x10\n ? skb_network_protocol+0xce/0x2d0\n ? dev_hard_start_xmit+0xca/0x350\n ? __pfx_vxlan_xmit+0x10/0x10\n dev_hard_start_xmit+0xca/0x350\n __dev_queue_xmit+0x513/0x1e20\n ? __pfx___dev_queue_xmit+0x10/0x10\n ? __pfx_lock_release+0x10/0x10\n ? mark_held_locks+0x44/0x90\n ? skb_push+0x4c/0x80\n ? eth_header+0x81/0xe0\n ? __pfx_eth_header+0x10/0x10\n ? neigh_resolve_output+0x215/0x310\n ? ip6_finish_output2+0x2ba/0xc90\n ip6_finish_output2+0x2ba/0xc90\n ? lock_release+0x236/0x3e0\n ? ip6_mtu+0xbb/0x240\n ? __pfx_ip6_finish_output2+0x10/0x10\n ? find_held_lock+0x83/0xa0\n ? lock_is_held_type+0xe7/0x140\n ip6_finish_output+0x1ee/0x780\n ip6_output+0x138/0x460\n ? __pfx_ip6_output+0x10/0x10\n ? __pfx___lock_acquire+0x10/0x10\n ? __pfx_ip6_finish_output+0x10/0x10\n NF_HOOK.constprop.0+0xc0/0x420\n ? __pfx_NF_HOOK.constprop.0+0x10/0x10\n ? ndisc_send_skb+0x2c0/0x960\n ? __pfx_lock_release+0x10/0x10\n ? __local_bh_enable_ip+0x93/0x110\n ? lock_is_held_type+0xe7/0x140\n ndisc_send_skb+0x4be/0x960\n ? __pfx_ndisc_send_skb+0x10/0x10\n ? mark_held_locks+0x65/0x90\n ? find_held_lock+0x83/0xa0\n ndisc_send_ns+0xb0/0x110\n ? __pfx_ndisc_send_ns+0x10/0x10\n addrconf_dad_work+0x631/0x8e0\n ? lock_acquire+0x180/0x3f0\n ? __pfx_addrconf_dad_work+0x10/0x10\n ? mark_held_locks+0x24/0x90\n process_one_work+0x582/0x9c0\n ? __pfx_process_one_work+0x10/0x10\n ? __pfx_do_raw_spin_lock+0x10/0x10\n ? mark_held_locks+0x24/0x90\n worker_thread+0x93/0x630\n ? __kthread_parkme+0xdc/0x100\n ? __pfx_worker_thread+0x10/0x10\n kthread+0x1a5/0x1e0\n ? __pfx_kthread+0x10/0x10\n ret_from_fork+0x34/0x60\n \n---truncated---",

"text": "In the Linux kernel, the following vulnerability has been resolved:\n\nrxrpc: Make it so that a waiting process can be aborted\n\nWhen sendmsg() creates an rxrpc call, it queues it to wait for a connection\nand channel to be assigned and then waits before it can start shovelling\ndata as the encrypted DATA packet content includes a summary of the\nconnection parameters.\n\nHowever, sendmsg() may get interrupted before a connection gets assigned\nand further sendmsg() calls will fail with EBUSY until an assignment is\nmade.\n\nFix this so that the call can at least be aborted without failing on\nEBUSY. We have to be careful here as sendmsg() mustn't be allowed to start\nthe call timer if the call doesn't yet have a connection assigned as an\noops may follow shortly thereafter.",

"text": "In the Linux kernel, the following vulnerability has been resolved:\n\nnfsd: handle get_client_locked() failure in nfsd4_setclientid_confirm()\n\nLei Lu recently reported that nfsd4_setclientid_confirm() did not check\nthe return value from get_client_locked(). a SETCLIENTID_CONFIRM could\nrace with a confirmed client expiring and fail to get a reference. That\ncould later lead to a UAF.\n\nFix this by getting a reference early in the case where there is an\nextant confirmed client. If that fails then treat it as if there were no\nconfirmed client found at all.\n\nIn the case where the unconfirmed client is expiring, just fail and\nreturn the result from get_client_locked().",

"text": "In the Linux kernel, the following vulnerability has been resolved:\nPCI: Fix pci_device_is_present() for VFs by checking PF\npci_device_is_present() previously didn't work for VFs because it reads the\nVendor and Device ID, which are 0xffff for VFs, which looks like they\naren't present. Check the PF instead.\nWei Gong reported that if virtio I/O is in progress when the driver is\nunbound or \"0\" is written to /sys/.../sriov_numvfs, the virtio I/O\noperation hangs, which may result in output like this:\ntask:bash state:D stack: 0 pid: 1773 ppid: 1241 flags:0x00004002\nCall Trace:\nschedule+0x4f/0xc0\nblk_mq_freeze_queue_wait+0x69/0xa0\nblk_mq_freeze_queue+0x1b/0x20\nblk_cleanup_queue+0x3d/0xd0\nvirtblk_remove+0x3c/0xb0 [virtio_blk]\nvirtio_dev_remove+0x4b/0x80\n...\ndevice_unregister+0x1b/0x60\nunregister_virtio_device+0x18/0x30\nvirtio_pci_remove+0x41/0x80\npci_device_remove+0x3e/0xb0\nThis happened because pci_device_is_present(VF) returned \"false\" in\nvirtio_pci_remove(), so it called virtio_break_device(). The broken vq\nmeant that vring_interrupt() skipped the vq.callback() that would have\ncompleted the virtio I/O operation via virtblk_done().\n[bhelgaas: commit log, simplify to always use pci_physfn(), add stable tag]",
