High impact if exploited, but EPSS currently rates exploitation as unlikely (0.14%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
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)
