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"}}]}}
