Description OSIDB Bzimport 2026-11-10 19:19:14 UTC 
FFmpeg 8.0 through 9.0.2 contains a memory leak vulnerability in the VP9 decoder that allows attackers to exhaust memory because vp9_decode_frame() skips resetting the CBS fragment on error paths. Attackers can supply a crafted VP9 stream with invalid tile sizes decoded with slice threading to leak packet buffers and units, exhausting memory in the decoding application.
