kthreads_online_cpu+0x140/0x140\nret_from_fork_asm+0x11/0x20\n\nThe cause of this is:\n- drm_prime_gem_destroy calls dma_buf_put(dma_buf) which releases the\nreference to the shared dma_buf. The reference count is 0, so the\ndma_buf is destroyed, which in turn decrements the corresponding\namdgpu_bo reference count to 0, and the amdgpu_bo is destroyed -\ncalling drm_gem_object_release then dma_resv_fini (which destroys the\nreservation object), then finally freeing the amdgpu_bo.\n- nouveau_bo obj->bo.base.resv is now a dangling pointer to the memory\nformerly allocated to the amdgpu_bo.\n- nouveau_gem_object_del calls ttm_bo_put(&nvbo->bo) which calls\nttm_bo_release, which schedules ttm_bo_delayed_delete.\n- ttm_bo_delayed_delete runs and dereferences the dangling resv pointer,\nresulting in a general protection fault.\nFix this by moving the drm_prime_gem_destroy call from\nnouveau_gem_object_del to nouveau_bo_del_ttm. This ensures that it will\nbe run after ttm_bo_delayed_delete.", "title": "Vulnerability description" }, { "category": "general", "text": "The CVSS score(s) listed for this vulnerability do not reflect the associated product's status, and are included for informational purposes to better understand the severity of this vulnerability.", "title": "CVSS score applicability" } ], "product_status": { "fixed": [ "Oracle-Linux-7:bpftool-0:5.4.17-2136.338.4.2.el7uek.tuxcare.els2.x86_64", "Oracle-Linux-7:kernel-uek-tools-0:5.4.17-2136.338.4.2.el7uek.tuxcare.els2.x86_64", "Oracle-Linux-7:kernel-uek-container-0:5.4.17-2136.338.4.2.el7uek.tuxcare.els2.x86_64", "Oracle-Linux-7:kernel-uek-0:5.4.17-2136.338.4.2.el7uek.tuxcare.els2.x86_64", "Oracle-Linux-7:kernel-uek-devel-0:5.4.17-2136.338.4.2.el7uek.tuxcare.els2.x86_64", "Oracle-Linux-7:python-perf-0:5.4.17-2136.338.4.2.el7uek.tuxcare.els2.x86_64", "Oracle-Linux-7:perf-0:5.4.17-2136.338.4.2.el7uek.tuxcare.els2.x86_64", "Oracle-Linux-7:kernel-uek-headers-0:5.4.17-2136.338.4.2.el7uek.tuxcare.els2.x86_64", "Oracle-Linux-7:kernel-uek-debug-devel-0:5.4.17-2136.338.4.2.el7uek.tuxcare.els2.x86_64", "Oracle-Linux-7:kernel-uek-container-debug-0:5.4.17-2136.338.4.2.el7uek.tuxcare.els2.x86_64", "Oracle-Linux-7:kernel-uek-debug-0:5.4.17-2136.338.4.2.el7uek.tuxcare.els2.x86_64" ] }, "references": [ { "category": "self", "summary": "Canonical URL", "url": "https://cve.tuxcare.com/els/cve/CVE-2025-37765" } ], "release_date": "2025-05-01T00:00:00", "scores": [ { "cvss_v3": { "attackComplexity": "LOW", "attackVector": "LOCAL", "availabilityImpact": "HIGH", "baseScore": 5.5, "baseSeverity": "MEDIUM", "confidentialityImpact": "NONE", "integrityImpact": "NONE", "privilegesRequired": "LOW", "scope": "UNCHANGED", "userInteraction": "NONE", "vectorString": "CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H", "version": "3.1" }, "products": [ "Oracle-Linux-7:bpftool-0:5.4.17-2136.338.4.2.el7uek.tuxcare.els2.x86_64", "Oracle-Linux-7:kernel-uek-tools-0:5.4.17-2136.338.4.2.el7uek.tuxcare.els2.x86_64", "Oracle-Linux-7:kernel-uek-container-0:5.4.17-2136.338.4.2.el7uek.tuxcare.els2.x86_64", "Oracle-Linux-7:kernel-uek-0:5.4.17-2136.338.4.2.el7uek.tuxcare.els2.x86_64", "Oracle-Linux-7:kernel-uek-devel-0:5.4.17-2136.338.4.2.el7uek.tuxcare.els2.x86_64", "Oracle-Linux-7:python-perf-0:5.4.17-2136.338.4.2.el7uek.tuxcare.els2.x86_64", "Oracle-Linux-7:perf-0:5.4.17-2136.338.4.2.el7uek.tuxcare.els2.x86_64", "Oracle-Linux-7:kernel-uek-headers-0:5.4.17-2136.338.4.2.el7uek.tuxcare.els2.x86_64", "Oracle-Linux-7:kernel-uek-debug-devel-0:5.4.17-2136.338.4.2.el7uek.tuxcare.els2.x86_64", "Oracle-Linux-7:kernel-uek-container-debug-0:5.4.17-2136.338.4.2.el7uek.tuxcare.els2.x86_64", "Oracle-Linux-7:kernel-uek-debug-0:5.4.17-2136.338.4.2.el7uek.tuxcare.els2.x86_64" ] } ], "threats": [ { "category": "impact", "details": "Medium" } ] } ] }
