AMDGPU_CS is gated by DRM_AUTH|DRM_RENDER_ALLOW, not root or special capabilities.\nUI:N - No victim interaction is required; the attacker drives the entire malicious command submission through the render node.\nS:C - Partial address patching causes VCE firmware to DMA using attacker-influenced GPU addresses outside the intended buffer object boundaries, crossing the GPU memory/DMA isolation boundary that the relocation logic is meant to enforce.\nC:H - VCE firmware performs DMA reads using the malformed 64-bit address, enabling arbitrary reads from GPU-accessible memory regions (including GTT-mapped system memory) beyond the validated buffer scope.\nI:H - VCE firmware performs DMA writes (encoded bitstreams, feedback, and context buffers) to attacker-influenced addresses, enabling arbitrary GPU-mapped memory corruption and potential privilege escalation primitives.\nA:H - Submitting commands with malformed firmware addresses can cause GPU page faults, driver hangs, GPU resets, or kernel oops/panic when the VCE engine accesses invalid memory regions." } ] } ], "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_vce.c" ], "versions": [ { "version": "d38ceaf99ed015f2a0b9af3499791bd3a3daae21", "lessThan": "2d66d1f5d8c0434e9a5ad21cc6eaf3a5e32141d5", "status": "affected", "versionType": "git" }, { "version": "d38ceaf99ed015f2a0b9af3499791bd3a3daae21", "lessThan": "944db9cfa5373f67eb94621d4c2eee572c05fa3f", "status": "affected", "versionType": "git" }, { "version": "d38ceaf99ed015f2a0b9af3499791bd3a3daae21", "lessThan": "0ee17150763962671f43a62ddf8f6ea1feaff438", "status": "affected", "versionType": "git" }, { "version": "d38ceaf99ed015f2a0b9af3499791bd3a3daae21", "lessThan": "b3d1a0a45c4aec484fa2a5b060b611e3d3064470", "status": "affected", "versionType": "git" }, { "version": "d38ceaf99ed015f2a0b9af3499791bd3a3daae21", "lessThan": "ea2c554e700b86a04534b4c24ece5844e8c5f07e", "status": "affected", "versionType": "git" }, { "version": "d38ceaf99ed015f2a0b9af3499791bd3a3daae21", "lessThan": "de2a02cc28d6d5d37db07d00a9a684c754a5fd74", "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_vce.c" ], "versions": [ { "version": "4.2", "status": "affected" }, { "version": "0", "lessThan": "4.2", "status": "unaffected", "versionType": "semver" }, { "version": "6.1.175", "lessThanOrEqual": "6.1.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.6.140", "lessThanOrEqual": "6.6.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.12.90", "lessThanOrEqual": "6.12.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.18.32", "lessThanOrEqual": "6.18.*", "status": "unaffected", "versionType": "semver" }, { "version": "7.0.9", "lessThanOrEqual": "7.0.*", "status": "unaffected", "versionType": "semver" }, { "version": "7.1", "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": "6.1.175" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "4.2", "versionEndExcluding": "6.6.140" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "4.2", "versionEndExcluding": "6.12.90" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "4.2", "versionEndExcluding": "6.18.32" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "4.2", "versionEndExcluding": "7.0.9" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "4.2", "versionEndExcluding": "7.1" } ] } ] } ], "references": [ { "url": "https://git.kernel.org/stable/c/2d66d1f5d8c0434e9a5ad21cc6eaf3a5e32141d5" }, { "url": "https://git.kernel.org/stable/c/944db9cfa5373f67eb94621d4c2eee572c05fa3f" }, { "url": "https://git.kernel.org/stable/c/0ee17150763962671f43a62ddf8f6ea1feaff438" }, { "url": "https://git.kernel.org/stable/c/b3d1a0a45c4aec484fa2a5b060b611e3d3064470" }, { "url": "https://git.kernel.org/stable/c/ea2c554e700b86a04534b4c24ece5844e8c5f07e" }, { "url": "https://git.kernel.org/stable/c/de2a02cc28d6d5d37db07d00a9a684c754a5fd74" } ], "title": "drm/amdgpu/vce: Prevent partial address patches", "x_generator": { "engine": "bippy-1.2.0" } } } }
