Attackers can craft Hap video frames with Snappy length prefixes that wrap tex_size, causing decompress_chunks_thread() to write outside tex_buf and crash the application or potentially execute code.","published":"2026-11-09T19:16:59.640","modified":"2026-11-09T19:16:59.640","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":{"url":"https://github.com/FFmpeg/FFmpeg/commit/62c308e0416bb701447817fe6f0bff074d206215","label":"FFmpeg/FFmpeg@62c308e"},"references":[{"type":"WEB","url":"https://code.ffmpeg.org/FFmpeg/FFmpeg/pulls/25702"},{"type":"WEB","url":"https://github.com/FFmpeg/FFmpeg"},{"type":"WEB","url":"https://github.com/FFmpeg/FFmpeg/blob/n9.0.2/libavcodec/hapdec.c#L215"},{"type":"WEB","url":"https://github.com/FFmpeg/FFmpeg/commit/62c308e0416bb701447817fe6f0bff074d206215"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/ffmpeg-through-9.0.2-heap-buffer-overflow-via-hap-parse-frame-header"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-11-09T19:16:59.640"}}
