there is no remote or adjacent-network reachability.\nAC:L - The attacker deterministically triggers the type confusion by binding/unbinding the writeback connector's CRTC_ID in a single atomic commit — no race, no timing window, and the affected hardware (all AMD DCN 3.0+ GPUs) registers the writeback connector unconditionally in the default configuration.\nPR:L - Only an unprivileged local user with access to the DRM card node and DRM-master status is needed — the typical logged-in desktop/kiosk user via the uaccess ACL or video group, and any local user when no compositor holds master; the atomic and writeback client caps require no capabilities at all.\nUI:N - The attacker performs the atomic modeset ioctl entirely on their own; no victim action is required for the amdgpu_dm_commit_audio() path.\nS:U - The heap corruption occurs in kernel slab memory belonging to the same kernel security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - The cast produces out-of-bounds reads roughly 1 KB into the adjacent kmalloc-4k object (audio_inst at 5032, mst_root at 4952, freesync_vid_base at 5104), and the resulting controllable heap corruption can be leveraged into broader kernel memory disclosure.\nI:H - amdgpu_dm_commit_audio() performs a cross-object out-of-bounds write of 0xFFFFFFFF at a fixed offset in the neighbouring slab object, and get_highest_refresh_rate_mode() writes 120 bytes of attacker-influenced mode timings out of bounds — classic heap-spray-and-overwrite primitives usable for control-flow hijack.\nA:H - The out-of-bounds accesses corrupt adjacent slab objects and dereference garbage pointers (dm_resume() reads a bogus dc_link and dereferences it on every resume), reliably producing KASAN splats, oopses, and kernel panics." } ] } ], "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/display/amdgpu_dm/amdgpu_dm.c" ], "versions": [ { "version": "4562236b3bc0a28aeb6ee93b2d8a849a4c4e1c7c", "lessThan": "87de0a741ef6d93fcb99983138a0d89a546a043c", "status": "affected", "versionType": "git" }, { "version": "4562236b3bc0a28aeb6ee93b2d8a849a4c4e1c7c", "lessThan": "951a498fa993c5501994ec2df97c9297b02488c7", "status": "affected", "versionType": "git" }, { "version": "4562236b3bc0a28aeb6ee93b2d8a849a4c4e1c7c", "lessThan": "e9baa7110e9f3756bd5a812af376c288d9be894d", "status": "affected", "versionType": "git" }, { "version": "4562236b3bc0a28aeb6ee93b2d8a849a4c4e1c7c", "lessThan": "ecedd99a9369fb5cde601ae9abd58bca2739f1ae", "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/display/amdgpu_dm/amdgpu_dm.c" ], "versions": [ { "version": "4.15", "status": "affected" }, { "version": "0", "lessThan": "4.15", "status": "unaffected", "versionType": "semver" }, { "version": "6.1.116", "lessThanOrEqual": "6.1.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.6.31", "lessThanOrEqual": "6.6.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.8.10", "lessThanOrEqual": "6.8.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.9", "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": "4.15", "versionEndExcluding": "6.1.116" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "4.15", "versionEndExcluding": "6.6.31" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "4.15", "versionEndExcluding": "6.8.10" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "4.15", "versionEndExcluding": "6.9" } ] } ] } ], "references": [ { "url": "https://git.kernel.org/stable/c/87de0a741ef6d93fcb99983138a0d89a546a043c" }, { "url": "https://git.kernel.org/stable/c/951a498fa993c5501994ec2df97c9297b02488c7" }, { "url": "https://git.kernel.org/stable/c/e9baa7110e9f3756bd5a812af376c288d9be894d" }, { "url": "https://git.kernel.org/stable/c/ecedd99a9369fb5cde601ae9abd58bca2739f1ae" } ], "title": "drm/amd/display: Skip on writeback when it's not applicable", "x_generator": { "engine": "bippy-1.2.0" } }, "adp": [ { "title": "CISA ADP Vulnrichment", "metrics": [ { "other": { "type": "ssvc", "content": { "id": "CVE-2024-36914", "role": "CISA Coordinator", "options": [ { "Exploitation": "none" }, { "Automatable": "no" }, { "Technical Impact": "partial" } ], "version": "2.0.3", "timestamp": "2024-05-30T18:45:36.952476Z" } } } ], "providerMetadata": { "orgId": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "shortName": "CISA-ADP", "dateUpdated": "2024-06-04T17:48:03.591Z" } }, { "title": "CVE Program Container", "references": [ { "url": "https://git.kernel.org/stable/c/951a498fa993c5501994ec2df97c9297b02488c7", "tags": [ "x_transferred" ] }, { "url": "https://git.kernel.org/stable/c/e9baa7110e9f3756bd5a812af376c288d9be894d", "tags": [ "x_transferred" ] }, { "url": "https://git.kernel.org/stable/c/ecedd99a9369fb5cde601ae9abd58bca2739f1ae", "tags": [ "x_transferred" ] }, { "url": "https://lists.debian.org/debian-lts-announce/2025/01/msg00001.html" } ], "providerMetadata": { "orgId": "af854a3a-2127-422b-91ae-364da2661108", "shortName": "CVE", "dateUpdated": "2025-11-03T21:55:24.058Z" } } ] } }
