CVE-2026-80907Hinoki check available

Unspecified impact via incorrect H.264 DPB sizing

Published Sep 4, 2026 · Updated Sep 4, 2026

Incorrect buffer sizing in the Linux kernel AMDGPU UVD path allows attackers to trigger an unspecified impact via H.264 decode messages. The amdgpu_uvd_cs_msg_decode path derives the decoded-picture-buffer minimum from the H.264 level maximum instead of the actual reference count supplied in the decode message. Reachability requires a system using the AMDGPU UVD H.264 decode path; the Linux CVE team has not published a concrete confidentiality, integrity, or availability consequence.
