There is no network or adjacent-network path into amdgpu ring init.\nAC:L - In an affected configuration the ring type is a compile-time constant, so the out-of-bounds index is deterministic on every initialization — there is no race to win and no memory-layout condition to guess.\nPR:L - No capability check or privilege gate protects the array indexing itself; it runs as part of ordinary device attach/probe, and the resulting scheduler table is subsequently read and dereferenced on behalf of unprivileged local users holding a DRM render-node fd (amdgpu_ctx.c:163/229). Real root in the init namespace is not required to consume the corrupted state.\nUI:N - The write occurs automatically during driver/device initialization and the corrupted table is used by the attacker's own context-creation and command-submission ioctls; no action by another user or victim is needed.\nS:U - The corruption and its consequences are confined to the kernel of the machine running the driver, within `struct amdgpu_device`; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - The code reads a `num_scheds` counter from out-of-bounds memory and uses it as an unbounded write index, and the resulting corruption of adjacent `struct amdgpu_irq` state (interrupt source tables and callback pointers) is memory corruption that can be leveraged for disclosure of kernel memory.\nI:H - This is an out-of-bounds write of a kernel pointer (`&ring->sched`) past `gpu_sched[][]` at an index taken from out-of-bounds memory, overwriting adjacent interrupt-handling structures in `struct amdgpu_device`; per kernel scoring guidance an OOB write with a corrupted destination index is High, as it can be leveraged toward control-flow hijack.\nA:H - Corrupting the scheduler table and adjacent irq structures leaves stale or wild `drm_gpu_scheduler` pointers that are later dereferenced during entity setup and interrupt dispatch, producing a kernel oops and a wedged GPU/system." } ] } ], "affected": [ { "product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": [ "drivers/gpu/drm/amd/amdgpu/amdgpu_ring.c" ], "versions": [ { "version": "d38ceaf99ed015f2a0b9af3499791bd3a3daae21", "lessThan": "c253b87c7c37ec40a2e0c84e4a6b636ba5cd66b2", "status": "affected", "versionType": "git" }, { "version": "d38ceaf99ed015f2a0b9af3499791bd3a3daae21", "lessThan": "919f9bf9997b8dcdc132485ea96121e7d15555f9", "status": "affected", "versionType": "git" }, { "version": "d38ceaf99ed015f2a0b9af3499791bd3a3daae21", "lessThan": "cf2db220b38301b6486a0f11da24a0f317de558c", "status": "affected", "versionType": "git" }, { "version": "d38ceaf99ed015f2a0b9af3499791bd3a3daae21", "lessThan": "a60d1f7ff62e453dde2d3b4907e178954d199844", "status": "affected", "versionType": "git" }, { "version": "d38ceaf99ed015f2a0b9af3499791bd3a3daae21", "lessThan": "130bee397b9cd52006145c87a456fd8719390cb5", "status": "affected", "versionType": "git" }, { "version": "d38ceaf99ed015f2a0b9af3499791bd3a3daae21", "lessThan": "be1684930f5262a622d40ce7a6f1423530d87f89", "status": "affected", "versionType": "git" } ] }, { "product": "Linux", "vendor": "Linux", "defaultStatus": "affected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": [ "drivers/gpu/drm/amd/amdgpu/amdgpu_ring.c" ], "versions": [ { "version": "4.2", "status": "affected" }, { "version": "0", "lessThan": "4.2", "status": "unaffected", "versionType": "semver" }, { "version": "5.10.226", "lessThanOrEqual": "5.10.*", "status": "unaffected", "versionType": "semver" }, { "version": "5.15.167", "lessThanOrEqual": "5.15.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.1.109", "lessThanOrEqual": "6.1.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.6.50", "lessThanOrEqual": "6.6.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.10.9", "lessThanOrEqual": "6.10.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.11", "lessThanOrEqual": "*", "status": "unaffected", "versionType": "original_commit_for_fix" } ] } ], "cpeApplicability": [ { "nodes": [ { "operator": "OR", "negate": false, "cpeMatch": [ { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "4.2", "versionEndExcluding": "5.10.226" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "4.2", "versionEndExcluding": "5.15.167" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "4.2", "versionEndExcluding": "6.1.109" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "4.2", "versionEndExcluding": "6.6.50" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "4.2", "versionEndExcluding": "6.10.9" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "4.2", "versionEndExcluding": "6.11" } ] } ] } ], "references": [ { "url": "https://git.kernel.org/stable/c/c253b87c7c37ec40a2e0c84e4a6b636ba5cd66b2" }, { "url": "https://git.kernel.org/stable/c/919f9bf9997b8dcdc132485ea96121e7d15555f9" }, { "url": "https://git.kernel.org/stable/c/cf2db220b38301b6486a0f11da24a0f317de558c" }, { "url": "https://git.kernel.org/stable/c/a60d1f7ff62e453dde2d3b4907e178954d199844" }, { "url": "https://git.kernel.org/stable/c/130bee397b9cd52006145c87a456fd8719390cb5" }, { "url": "https://git.kernel.org/stable/c/be1684930f5262a622d40ce7a6f1423530d87f89" } ], "title": "drm/amdgpu: Fix out-of-bounds write warning", "x_generator": { "engine": "bippy-1.2.0" } }, "adp": [ { "metrics": [ { "other": { "type": "ssvc", "content": { "timestamp": "2024-09-29T14:55:45.774972Z", "id": "CVE-2024-46725", "options": [ { "Exploitation": "none" }, { "Automatable": "no" }, { "Technical Impact": "partial" } ], "role": "CISA Coordinator", "version": "2.0.3" } } } ], "title": "CISA ADP Vulnrichment", "providerMetadata": { "orgId": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "shortName": "CISA-ADP", "dateUpdated": "2024-09-29T14:56:00.445Z" } }, { "title": "CVE Program Container", "references": [ { "url": "https://lists.debian.org/debian-lts-announce/2025/01/msg00001.html" }, { "url": "https://lists.debian.org/debian-lts-announce/2024/10/msg00003.html" } ], "providerMetadata": { "orgId": "af854a3a-2127-422b-91ae-364da2661108", "shortName": "CVE", "dateUpdated": "2025-11-03T22:17:08.917Z" } } ] } }
