DescriptionCVE.org

In the Linux kernel, the following vulnerability has been resolved:

drm/amdgpu: fix division by zero with invalid uvd dimensions

When width or height is less than 16, width_in_mb or height_in_mb becomes 0, leading to fs_in_mb being 0. This causes a division by zero when calculating num_dpb_buffer in H264 and H264 Perf decode paths.

Add validation to reject frames with width < 16 or height < 16 before performing any calculations that depend on these values.

V2: Format change - move up all vaiable definitions. V3: Use warn_once to avoid spam.

(cherry picked from commit 3e41d26c70b0a459d041cc19482a226c4b7423cb)

AnalysisAI

Division by zero in the Linux kernel's amdgpu DRM subsystem (drm/amdgpu UVD driver) allows a local attacker with access to AMD GPU render nodes to crash the kernel or potentially escalate privileges by submitting H264 video decode requests with frame dimensions below 16 pixels. Affected stable branches span kernel versions prior to 6.6.148, 6.12.101, 6.18.42, and 7.1.6, all of which now have upstream patches committed. No public exploit code and no CISA KEV listing have been identified; EPSS at 0.17% (6th percentile) indicates negligible near-term automated exploitation probability.

Technical ContextAI

The vulnerability exists within the amdgpu kernel driver's UVD (Unified Video Decoder) hardware abstraction layer, responsible for offloading H264 video decode operations to AMD GPU silicon. During buffer allocation for H264 and H264 Perf decode paths, the code derives macroblock-aligned dimensions by dividing the frame width and height by 16 (the standard H264 macroblock size). When the supplied width or height is less than 16, integer division produces a zero-valued width_in_mb or height_in_mb, which propagates to fs_in_mb. A subsequent division using this zero value triggers a kernel divide-by-zero exception - a CWE-369 class defect, though NVD has not formally assigned a CWE. The CPE cpe:2.3:a:linux:linux:* confirms broad Linux kernel applicability, though the vulnerable code path is gated behind AMD GPU hardware with UVD support. The fix adds input guards rejecting frames with width or height below 16 before any macroblock arithmetic.

RemediationAI

The primary fix is to upgrade the Linux kernel to a patched stable release: 6.6.148, 6.12.101, 6.18.42, or 7.1.6 depending on the branch in use. Distribution maintainers for Red Hat, Debian, Ubuntu, SUSE, and Arch should be publishing updated kernel packages tracking these stable tags; apply via standard package management. As a compensating control where immediate kernel upgrade is not feasible, restrict access to DRM render nodes by removing non-essential users from the video and render groups and tightening permissions on /dev/dri/renderD* device files (e.g., chmod 600 or removing group read/write). This prevents unprivileged users from submitting UVD decode requests and closes the local exploitation path, though it will break GPU-accelerated video decode for those users in applications such as FFmpeg, GStreamer, and media players using VA-API or VDPAU. Systems without AMD GPU hardware or with the amdgpu driver not loaded are not exposed and require no action beyond normal patching cadence.
