Severity ?
7.8 (High) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Summary
In the Linux kernel, the following vulnerability has been resolved: nouveau/gem: reserve the bo in the info ioctl around the vma lookup In the non-uvmm path, there could be a race between the info lookup finding the vma, and the gem close path closing the vma leading to a use-after-free. Spotted with the help of Opus 4.6.

Not reachable from network protocols, adjacent radios, or physical buses.\nAC:L - The attacker controls both sides of the race with threads that GEM_INFO and GEM_CLOSE the same handle, so close kfree()s the nouveau_vma while info still uses it.

Any unprivileged local user who can open the nouveau render node (typical render/video group or uaccess ACL) can trigger it without init-namespace root.\nUI:N - Exploitation needs only the attacker opening their own DRM client, creating a GEM BO, and racing GEM_INFO against GEM_CLOSE on that handle; no separate victim action is required.\nS:U - The use-after-free corrupts kernel heap state (struct nouveau_vma) inside the host nouveau driver. Impact stays in the same kernel authority; this is not a VM escape or IOMMU/DMA isolation bypass.\nC:H - Use-after-free of struct nouveau_vma lets GEM_INFO read vma-\u003eaddr after kfree, and concurrent walks of nvbo-\u003evma_list can follow attacker-reused slab objects, enabling kernel memory disclosure as with other UAFs.\nI:H - UAF of the VMA plus concurrent list_del/list_del_init on nvbo-\u003evma_list enables heap spraying and list-pointer corruption, supporting arbitrary kernel writes and control-flow hijack as with other kernel UAFs.\nA:H - Dereferencing a freed nouveau_vma in GEM_INFO or walking a concurrently deleted vma_list causes a kernel oops/panic; the attacker can repeat the race to crash or hang the system."

Not reachable from network protocols, adjacent radios, or physical buses.\\nAC:L - The attacker controls both sides of the race with threads that GEM_INFO and GEM_CLOSE the same handle, so close kfree()s the nouveau_vma while info still uses it. Skipping UVMM (legacy GEM_NEW) selects the vulnerable path; no victim timing or rare config is required.\\nPR:L - NOUVEAU_GEM_INFO and GEM_CLOSE are DRM_RENDER_ALLOW with no DRM_ROOT_ONLY or capability checks. Any unprivileged local user who can open the nouveau render node (typical render/video group or uaccess ACL) can trigger it without init-namespace root.\\nUI:N - Exploitation needs only the attacker opening their own DRM client, creating a GEM BO, and racing GEM_INFO against GEM_CLOSE on that handle; no separate victim action is required.\\nS:U - The use-after-free corrupts kernel heap state (struct nouveau_vma) inside the host nouveau driver. Impact stays in the same kernel authority; this is not a VM escape or IOMMU/DMA isolation bypass.\\nC:H - Use-after-free of struct nouveau_vma lets GEM_INFO read vma-\u003eaddr after kfree, and concurrent walks of nvbo-\u003evma_list can follow attacker-reused slab objects, enabling kernel memory disclosure as with other UAFs.\\nI:H - UAF of the VMA plus concurrent list_del/list_del_init on nvbo-\u003evma_list enables heap spraying and list-pointer corruption, supporting arbitrary kernel writes and control-flow hijack as with other kernel UAFs.\\nA:H - Dereferencing a freed nouveau_vma in GEM_INFO or walking a concurrently deleted vma_list causes a kernel oops/panic; the attacker can repeat the race to crash or hang the system.\"}]}], \"affected\": [{\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\", \"product\": \"Linux\", \"versions\": [{\"status\": \"affected\", \"version\": \"e758a3111914af7ee4351be86f1ac0efe87ed06e\", \"lessThan\": \"e05c28bd6043d0fd0bea9c3fc49300a8871a1a81\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"e758a3111914af7ee4351be86f1ac0efe87ed06e\", \"lessThan\": \"208867763843aa82efcbe3b771f1b8e6c7aa820a\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"e758a3111914af7ee4351be86f1ac0efe87ed06e\", \"lessThan\": \"ff110e85837d7ecd83f36078107be240ff5ae409\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"e758a3111914af7ee4351be86f1ac0efe87ed06e\", \"lessThan\": \"e60466011ac3a6b8045e6cc3c2cbb30d58039d2e\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"e758a3111914af7ee4351be86f1ac0efe87ed06e\", \"lessThan\": \"5e17160d41d92823f3379c1982e1369680c5ce4d\", \"versionType\": \"git\"}], \"programFiles\": [\"drivers/gpu/drm/nouveau/nouveau_gem.c\"], \"defaultStatus\": \"unaffected\"}, {\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\", \"product\": \"Linux\", \"versions\": [{\"status\": \"affected\", \"version\": \"3.1\"}, {\"status\": \"unaffected\", \"version\": \"0\", \"lessThan\": \"3.1\", \"versionType\": \"semver\"}, {\"status\": \"unaffected\", \"version\": \"6.6.157\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.6.*\"}, {\"status\": \"unaffected\", \"version\": \"6.12.109\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.12.*\"}, {\"status\": \"unaffected\", \"version\": \"6.18.50\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.18.*\"}, {\"status\": \"unaffected\", \"version\": \"7.2.4\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"7.2.*\"}, {\"status\": \"unaffected\", \"version\": \"7.3\", \"versionType\": \"original_commit_for_fix\", \"lessThanOrEqual\": \"*\"}], \"programFiles\": [\"drivers/gpu/drm/nouveau/nouveau_gem.c\"], \"defaultStatus\": \"affected\"}], \"references\": [{\"url\": \"https://git.kernel.org/stable/c/e05c28bd6043d0fd0bea9c3fc49300a8871a1a81\"}, {\"url\": \"https://git.kernel.org/stable/c/208867763843aa82efcbe3b771f1b8e6c7aa820a\"}, {\"url\": \"https://git.kernel.org/stable/c/ff110e85837d7ecd83f36078107be240ff5ae409\"}, {\"url\": \"https://git.kernel.org/stable/c/e60466011ac3a6b8045e6cc3c2cbb30d58039d2e\"}, {\"url\": \"https://git.kernel.org/stable/c/5e17160d41d92823f3379c1982e1369680c5ce4d\"}], \"x_generator\": {\"engine\": \"bippy-1.2.0\"}, \"descriptions\": [{\"lang\": \"en\", \"value\": \"In the Linux kernel, the following vulnerability has been resolved:\\n\\nnouveau/gem: reserve the bo in the info ioctl around the vma lookup\\n\\nIn the non-uvmm path, there could be a race between the info lookup\\nfinding the vma, and the gem close path closing the vma leading\\nto a use-after-free.\\n\\nSpotted with the help of Opus 4.6.\"}], \"cpeApplicability\": [{\"nodes\": [{\"negate\": false, \"cpeMatch\": [{\"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"vulnerable\": true, \"versionEndExcluding\": \"6.6.157\", \"versionStartIncluding\": \"3.1\"}, {\"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"vulnerable\": true, \"versionEndExcluding\": \"6.12.109\", \"versionStartIncluding\": \"3.1\"}, {\"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"vulnerable\": true, \"versionEndExcluding\": \"6.18.50\", \"versionStartIncluding\": \"3.1\"}, {\"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"vulnerable\": true, \"versionEndExcluding\": \"7.2.4\", \"versionStartIncluding\": \"3.1\"}, {\"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"vulnerable\": true, \"versionEndExcluding\": \"7.3\", \"versionStartIncluding\": \"3.1\"}], \"operator\": \"OR\"}]}], \"providerMetadata\": {\"orgId\": \"416baaa9-dc9f-4396-8d5f-8c081fb06d67\", \"shortName\": \"Linux\", \"dateUpdated\": \"2026-10-19T08:48:46.072Z\"}}}",
