CVE-2026-125194 · Runtime
NO FIX YET · SEE WHAT TO DO
FFmpeg's DVD PCM encoder reads past the end of a buffer when the final 24-bit audio frame is shorter than one block. An attacker who supplies crafted 24-bit 48 or 96 kHz audio can crash the transcoding process.

Systems that run FFmpeg to transcode user-supplied 24-bit DVD audio are exposed. Pipelines that only process trusted media, or that do not run FFmpeg, can skip it. The sources do not name the affected version range beyond 'through 9.0.2'.

Who cares ffmpeg, media-processing, transcoding
ffmpeg -version.FFmpeg through 9.0.2 contains an out-of-bounds read vulnerability in pcm_dvd_encode_frame() in libavcodec/pcm-dvdenc.c when a 24-bit final frame holds fewer samples than one block. Attackers can supply 24-bit 48 or 96 kHz audio whose length leaves a short final frame, causing the loop counter to wrap and crash the transcoding process.
