Attackers can supply crafted HEVC bitstreams with excessive tile columns or rows to write controlled 16-bit values past heap-allocated hwaccel data, corrupting memory in applications using VDPAU decoding.","published":"2026-11-09T19:16:59.193","modified":"2026-11-09T19:16:59.193","cvss":{"score":7,"severity":"HIGH","vector":"CVSS:3.1/AV:L/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":null,"references":[{"type":"WEB","url":"https://code.ffmpeg.org/FFmpeg/FFmpeg/pulls/25136"},{"type":"WEB","url":"https://github.com/FFmpeg/FFmpeg"},{"type":"WEB","url":"https://github.com/FFmpeg/FFmpeg/blob/n9.0.2/libavcodec/vdpau_hevc.c#L163"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/ffmpeg-through-9.0.2-heap-buffer-overflow-via-hevc-vdpau-tile-arrays"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-11-09T19:16:59.193"}}
