FFmpeg before 8.1.3 and 9.x before 9.0.2 contains an out-of-bounds read vulnerability in put_vector() in libavcodec/vorbisenc.c when NaN samples leave the codebook entry at -1. Attackers can supply audio with NaN float samples to the native Vorbis encoder, causing heap reads before arrays that crash the application or leak adjacent heap memory into output.
