Summary

The avcodec_decode_audio4 function in utils.c in libavcodec in FFmpeg before 1.1.3 does not verify the decoding state before proceeding with certain skip operations, which allows remote attackers to cause a denial of service (out-of-bounds array access and application crash) or possibly have unspecified other impact via crafted audio data.

Exploit prediction

1.39% chance of exploitation in the next 30 days, higher than 72% of all scored CVEs (FIRST EPSS, 2026-11-09).
