CVE-2026-68108
Detail
Received This CVE record has recently been published to the CVE List and has been included within the NVD dataset.
Description
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)
