there is no network-facing entry point.\nAC:L - Once the AMDGPU ACP block has been initialized, calling acp_hw_fini deterministically frees acp_genpd without unregistering it from the global genpd list; no race or special memory layout is required to leave a dangling list entry.\nPR:L - Unprivileged users with access to /dev/dri/renderD* can autoload amdgpu and trigger the fini path if initialization fails after ACP setup; the same bug also fires on privileged driver unload/hot-unplug teardown of AMDGPU on ACP-capable APUs (Carrizo/Stoney).\nUI:N - Exploitation does not require any victim interaction such as clicking links or mounting filesystems; triggering driver teardown or a failed init cleanup is sufficient once the attacker can open the DRM device or unload the driver.\nS:U - The use-after-free corrupts kernel heap metadata/objects in the same kernel security domain during AMDGPU/ACP teardown; it does not by itself cross VM, container, or IOMMU boundaries to impact a separate authority.\nC:H - Freeing the generic_pm_domain while it remains linked on the global gpd_list is a kernel use-after-free; subsequent genpd list walks can read attacker-influenced freed memory, enabling information disclosure and kernel pointer leaks.\nI:H - The dangling genpd entry allows the power-domain core to perform reads/writes through a freed acp_pm_domain/generic_pm_domain object, providing a standard heap UAF primitive that can be developed into arbitrary kernel memory corruption or code execution.\nA:H - Dereferencing the freed genpd from the global list during later power-management operations can cause kernel oops/panic or hang, and the UAF can be leveraged for a reliable denial-of-service even when full exploitation is not attempted."}]}], "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_acp.c"], "versions": [{"version": "25030321ba2860c56651429a4f28d94a6483d952", "lessThan": "bdfc7f1e0900ef1361b828c4f69b72701f8a0a86", "status": "affected", "versionType": "git"}, {"version": "25030321ba2860c56651429a4f28d94a6483d952", "lessThan": "5c0a82283271759fff445ac27182072f200a888c", "status": "affected", "versionType": "git"}, {"version": "25030321ba2860c56651429a4f28d94a6483d952", "lessThan": "08fee493e0261f9e4120a5c8e7e42e8a723574e8", "status": "affected", "versionType": "git"}, {"version": "25030321ba2860c56651429a4f28d94a6483d952", "lessThan": "930a5dc3df4aa5e10393134bd5313d616dbebaf6", "status": "affected", "versionType": "git"}, {"version": "25030321ba2860c56651429a4f28d94a6483d952", "lessThan": "28c9b3c5dc35cc790d11e26ca3fc6e068be63998", "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_acp.c"], "versions": [{"version": "4.6", "status": "affected"}, {"version": "0", "lessThan": "4.6", "status": "unaffected", "versionType": "semver"}, {"version": "6.6.148", "lessThanOrEqual": "6.6.*", "status": "unaffected", "versionType": "semver"}, {"version": "6.12.101", "lessThanOrEqual": "6.12.*", "status": "unaffected", "versionType": "semver"}, {"version": "6.18.42", "lessThanOrEqual": "6.18.*", "status": "unaffected", "versionType": "semver"}, {"version": "7.1.6", "lessThanOrEqual": "7.1.*", "status": "unaffected", "versionType": "semver"}, {"version": "7.2-rc2", "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": "4.6", "versionEndExcluding": "6.6.148"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "4.6", "versionEndExcluding": "6.12.101"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "4.6", "versionEndExcluding": "6.18.42"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "4.6", "versionEndExcluding": "7.1.6"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "4.6", "versionEndExcluding": "7.2-rc2"}]}]}], "references": [{"url": "https://git.kernel.org/stable/c/bdfc7f1e0900ef1361b828c4f69b72701f8a0a86"}, {"url": "https://git.kernel.org/stable/c/5c0a82283271759fff445ac27182072f200a888c"}, {"url": "https://git.kernel.org/stable/c/08fee493e0261f9e4120a5c8e7e42e8a723574e8"}, {"url": "https://git.kernel.org/stable/c/930a5dc3df4aa5e10393134bd5313d616dbebaf6"}, {"url": "https://git.kernel.org/stable/c/28c9b3c5dc35cc790d11e26ca3fc6e068be63998"}], "title": "drm/amdgpu: invoke pm_genpd_remove() before freeing genpd", "x_generator": {"engine": "bippy-1.2.0"}}}}
