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)

A fix is available. Apply it within your standard update timelines at low or medium mission impact and sooner than that at high.

Exploitation none (no KEV listing, exploit record or EPSS ≥ 50%) · Automatable unknown (not published for this CVE) · Technical impact partial (CVSS below 9.0). Mission impact is CISA's Mission & Well-being decision point, and only you can judge it: high means the affected system is essential to your organisation's mission, or its compromise could cause irreversible harm to people.
