Description

This security bulletin contains information about 1 vulnerability.


1) Integer overflow (CVE-ID: CVE-2026-68108)

CWE-ID: CWE-190 - Integer overflow

CVSSv4: 6.8 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a local user to cause out-of-bounds memory access.

The vulnerability exists due to integer overflow in amdgpu_vce_ring_parse_cs() in the VCE command stream parser when processing crafted VCE command streams with oversized image dimensions. A local user can submit a specially crafted command stream to cause out-of-bounds memory access.

The issue occurs when image dimensions wrap the calculated buffer size and bypass validation before reaching the GPU firmware.
