Vulnerability from cvelistv5
Published

Severity ?
8.8 (High) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H
Summary
In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu/vce: fix integer overflow in image size Fix a security vulnerability where malicious VCE command streams with oversized dimensions (e.g. 65536×65536) cause 32-bit integer overflow, wrapping the calculated buffer size to 0. This bypasses validation and allows GPU firmware to perform out-of-bound memory access. The fix uses 64-bit arithmetic to detect overflow and rejects invalid dimensions before they reach the hardware. V2: remove redundant check V3: modify max height value V4: remove size64 (cherry picked from commit cbe408dba581755ad1279a487ec786d8927d778d)

there is no network, adjacent-radio, or physical-device path to the VCE command-stream parser.\\nAC:L - On affected AMD GPUs using physical-mode VCE parsing, an attacker fully controls the IB and can set create-command dimensions (e.g., 65536x65536) to deterministically overflow the 32-bit size to zero without races or uncontrollable layout conditions.\\nPR:L - Exploitation requires only unprivileged local access to the amdgpu DRM render node; AMDGPU_CS is gated by DRM_AUTH|DRM_RENDER_ALLOW with no root, DRM-master, or non-namespace capability requirement.\\nUI:N - No victim interaction is needed beyond the attacker submitting crafted VCE command buffers through their own render-node context; no third party must open files or take other actions.\\nS:C - Bypassing size-based BO relocation/validation lets VCE firmware DMA outside the intended buffer boundaries, crossing the GPU memory-isolation boundary that kernel validation is meant to enforce on GART/VRAM mappings.\\nC:H - With validation defeated, VCE firmware can read arbitrarily beyond undersized encode/context/MV buffers, exposing other GPU-accessible memory including GTT-mapped system memory and adjacent VRAM allocations.\\nI:H - The same out-of-bounds VCE firmware accesses enable arbitrary writes to GPU-mapped memory beyond validated buffers, providing memory-corruption primitives suitable for privilege escalation or control-flow influence.\\nA:H - Oversized VCE operations against undersized buffers can trigger GPU page faults, engine hangs, GPU resets, or broader system disruption that the attacker can repeat via further command submissions.\"}]}], \"affected\": [{\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\", \"product\": \"Linux\", \"versions\": [{\"status\": \"affected\", \"version\": \"f1689ec1b0b1256d0e69653cd4aaeee44aafdf5c\", \"lessThan\": \"893db20383800cfe92e638705984eebb13bc81a5\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"f1689ec1b0b1256d0e69653cd4aaeee44aafdf5c\", \"lessThan\": \"a07430abd556de3707adfcadcc60db3fa64e4b2b\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"f1689ec1b0b1256d0e69653cd4aaeee44aafdf5c\", \"lessThan\": \"a6d7065b91a14790980ce6f4960db0ca8c3c9940\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"f1689ec1b0b1256d0e69653cd4aaeee44aafdf5c\", \"lessThan\": \"7eebef042c12dfe0568593ee6a8926d16505925e\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"f1689ec1b0b1256d0e69653cd4aaeee44aafdf5c\", \"lessThan\": \"00c311a13d225266800c712f2b7db2711c6897de\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"f1689ec1b0b1256d0e69653cd4aaeee44aafdf5c\", \"lessThan\": \"186bfdc4e26d019b2e7570cb121964a1d89b2e5b\", \"versionType\": \"git\"}], \"programFiles\": [\"drivers/gpu/drm/amd/amdgpu/amdgpu_vce.c\"], \"defaultStatus\": \"unaffected\"}, {\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\", \"product\": \"Linux\", \"versions\": [{\"status\": \"affected\", \"version\": \"4.2\"}, {\"status\": \"unaffected\", \"version\": \"0\", \"lessThan\": \"4.2\", \"versionType\": \"semver\"}, {\"status\": \"unaffected\", \"version\": \"6.1.183\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.1.*\"}, {\"status\": \"unaffected\", \"version\": \"6.6.148\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.6.*\"}, {\"status\": \"unaffected\", \"version\": \"6.12.101\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.12.*\"}, {\"status\": \"unaffected\", \"version\": \"6.18.42\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.18.*\"}, {\"status\": \"unaffected\", \"version\": \"7.1.6\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"7.1.*\"}, {\"status\": \"unaffected\", \"version\": \"7.2\", \"versionType\": \"original_commit_for_fix\", \"lessThanOrEqual\": \"*\"}], \"programFiles\": [\"drivers/gpu/drm/amd/amdgpu/amdgpu_vce.c\"], \"defaultStatus\": \"affected\"}], \"references\": [{\"url\": \"https://git.kernel.org/stable/c/893db20383800cfe92e638705984eebb13bc81a5\"}, {\"url\": \"https://git.kernel.org/stable/c/a07430abd556de3707adfcadcc60db3fa64e4b2b\"}, {\"url\": \"https://git.kernel.org/stable/c/a6d7065b91a14790980ce6f4960db0ca8c3c9940\"}, {\"url\": \"https://git.kernel.org/stable/c/7eebef042c12dfe0568593ee6a8926d16505925e\"}, {\"url\": \"https://git.kernel.org/stable/c/00c311a13d225266800c712f2b7db2711c6897de\"}, {\"url\": \"https://git.kernel.org/stable/c/186bfdc4e26d019b2e7570cb121964a1d89b2e5b\"}], \"x_generator\": {\"engine\": \"bippy-1.2.0\"}, \"descriptions\": [{\"lang\": \"en\", \"value\": \"In the Linux kernel, the following vulnerability has been resolved:\\n\\ndrm/amdgpu/vce: fix integer overflow in image size\\n\\nFix a security vulnerability where malicious VCE command streams\\nwith oversized dimensions (e.g. 65536\\u00d765536) cause 32-bit integer\\noverflow, wrapping the calculated buffer size to 0.
