Overview

What is CVE-2026-68108?

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)
