CVE-2026-125097 · Package
NO FIX YET
FFmpeg's raw video decoder does not check that packet stride covers a full row for 1 to 8 bits-per-pixel video. A crafted AVI, MOV or NUT file with truncated low bit depth packets can leak uninitialized heap memory into decoded frame output.

Systems that decode untrusted AVI, MOV or NUT files with FFmpeg, such as media-processing pipelines, upload transcoders or services that thumbnail user video, are the ones to look at. Deployments that only process trusted media, or that do not run FFmpeg on uploaded files, can likely skip it. The sources do not name the affected version range beyond 'through 9.0.2'.

Unknown from the sources.
No fix yet, per the sources.
FFmpeg through 9.0.2 contains an uninitialized memory disclosure vulnerability in raw_decode() in libavcodec/rawdec.c that fails to verify packet stride covers a full row for 1 to 8 bits per pixel video. Attackers can supply crafted AVI, MOV or NUT files with truncated low bit depth rawvideo packets to leak uninitialized heap memory through decoded frame output.
