There is no network, adjacent-radio, or physical-access path to this code.\nAC:L - Triggering is a single deterministic ioctl with an invalid domain bitmask (e.g. CPU|GTT|VRAM|DOORBELL); the attacker fully controls the domains field and needs no race, special memory layout, or victim state. Invalid combinations reliably exceed AMDGPU_BO_MAX_PLACEMENTS (3) and hit BUG_ON() on every attempt.\nPR:L - AMDGPU_GEM_CREATE is registered with DRM_AUTH|DRM_RENDER_ALLOW, so any local unprivileged user who can open the render node (default on desktops, ChromeOS, Steam Deck, and cloud GPU tenants via render/video group or ACL) can invoke it without real root or init-namespace capabilities.\nUI:N - The attacking process performs the GEM_CREATE ioctl itself; no other user must mount a filesystem, open a file, click a link, or take any other action for the invalid domain combination to reach amdgpu_bo_placement_from_domain() and panic the kernel.\nS:U - Impact is confined to host-kernel memory corruption and panic within the amdgpu/TTM driver; it does not cross a VM, IOMMU, or sandbox security boundary, and is standard local kernel privilege-escalation/DoS scope rather than a guest-to-host escape.\nC:H - Before BUG_ON(), amdgpu_bo_placement_from_domain() writes past the fixed placements[AMDGPU_BO_MAX_PLACEMENTS] array into adjacent amdgpu_bo fields (including struct ttm_placement) with attacker-influenced mem_type and flag values; this out-of-bounds write is memory corruption that could be leveraged for kernel info disclosure.\nI:H - The same out-of-bounds placement writes corrupt adjacent kernel heap objects in the amdgpu_bo allocation with partially attacker-controlled ttm_place contents; out-of-bounds writes into kernel structures are classed as high integrity impact and could enable further heap corruption or control-flow hijacking.\nA:H - Once placement count exceeds three the kernel hits BUG_ON(c > AMDGPU_BO_MAX_PLACEMENTS), causing an oops or panic; an unprivileged GPU client on shared AMD hardware (multi-user workstations or cloud GPU nodes) can repeatedly crash the entire host, denying service to all co-tenants."}]}], "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_gem.c"], "versions": [{"version": "77a2faa55c1a497f4e7e89eabd11830f0e3cb3dd", "lessThan": "5c73485af7ad9c3ae592db3481f370bc07705391", "status": "affected", "versionType": "git"}, {"version": "77a2faa55c1a497f4e7e89eabd11830f0e3cb3dd", "lessThan": "584e3d47736fe2e7184ef3fc16b00b41485f96c6", "status": "affected", "versionType": "git"}, {"version": "77a2faa55c1a497f4e7e89eabd11830f0e3cb3dd", "lessThan": "66133fc05c3af002f45de8a71b833c026ccbfba6", "status": "affected", "versionType": "git"}, {"version": "77a2faa55c1a497f4e7e89eabd11830f0e3cb3dd", "lessThan": "ce5da474c3ddf7cccec5dce6aa4296297dd7caff", "status": "affected", "versionType": "git"}, {"version": "77a2faa55c1a497f4e7e89eabd11830f0e3cb3dd", "lessThan": "493355096e397f9217b41c8574ed2784c7351443", "status": "affected", "versionType": "git"}, {"version": "77a2faa55c1a497f4e7e89eabd11830f0e3cb3dd", "lessThan": "220aa2589d7321fb68d2e8597862711b5f22ae0b", "status": "affected", "versionType": "git"}, {"version": "77a2faa55c1a497f4e7e89eabd11830f0e3cb3dd", "lessThan": "80f0b53860d02577709d69a312a29ca674b9297c", "status": "affected", "versionType": "git"}, {"version": "77a2faa55c1a497f4e7e89eabd11830f0e3cb3dd", "lessThan": "5e9d136ad74df4edec67e502ce267597064d8f86", "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_gem.c"], "versions": [{"version": "4.20", "status": "affected"}, {"version": "0", "lessThan": "4.20", "status": "unaffected", "versionType": "semver"}, {"version": "5.10.266", "lessThanOrEqual": "5.10.*", "status": "unaffected", "versionType": "semver"}, {"version": "5.15.217", "lessThanOrEqual": "5.15.*", "status": "unaffected", "versionType": "semver"}, {"version": "6.1.184", "lessThanOrEqual": "6.1.*", "status": "unaffected", "versionType": "semver"}, {"version": "6.6.153", "lessThanOrEqual": "6.6.*", "status": "unaffected", "versionType": "semver"}, {"version": "6.12.105", "lessThanOrEqual": "6.12.*", "status": "unaffected", "versionType": "semver"}, {"version": "6.18.46", "lessThanOrEqual": "6.18.*", "status": "unaffected", "versionType": "semver"}, {"version": "7.1.10", "lessThanOrEqual": "7.1.*", "status": "unaffected", "versionType": "semver"}, {"version": "7.2", "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": "4.20", "versionEndExcluding": "5.10.266"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "4.20", "versionEndExcluding": "5.15.217"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "4.20", "versionEndExcluding": "6.1.184"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "4.20", "versionEndExcluding": "6.6.153"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "4.20", "versionEndExcluding": "6.12.105"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "4.20", "versionEndExcluding": "6.18.46"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "4.20", "versionEndExcluding": "7.1.10"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "4.20", "versionEndExcluding": "7.2"}]}]}], "references": [{"url": "https://git.kernel.org/stable/c/5c73485af7ad9c3ae592db3481f370bc07705391"}, {"url": "https://git.kernel.org/stable/c/584e3d47736fe2e7184ef3fc16b00b41485f96c6"}, {"url": "https://git.kernel.org/stable/c/66133fc05c3af002f45de8a71b833c026ccbfba6"}, {"url": "https://git.kernel.org/stable/c/ce5da474c3ddf7cccec5dce6aa4296297dd7caff"}, {"url": "https://git.kernel.org/stable/c/493355096e397f9217b41c8574ed2784c7351443"}, {"url": "https://git.kernel.org/stable/c/220aa2589d7321fb68d2e8597862711b5f22ae0b"}, {"url": "https://git.kernel.org/stable/c/80f0b53860d02577709d69a312a29ca674b9297c"}, {"url": "https://git.kernel.org/stable/c/5e9d136ad74df4edec67e502ce267597064d8f86"}], "title": "drm/amdgpu: validate GEM_CREATE domain combinations", "x_generator": {"engine": "bippy-1.2.0"}}}}
