Description OSIDB Bzimport 2026-11-10 13:04:55 UTC 
FFmpeg through 9.0.2 contains a memory leak vulnerability in ff_mjpeg_decode_sof() in libavcodec/mjpegdec.c, which overwrites the hwaccel_picture_private pointer without freeing it. Attackers can supply crafted MJPEG streams with repeated SOF markers or failing frames to leak hwaccel private data and hardware buffers under VAAPI or NVDEC decoding.
