FFmpeg through 9.0.2 contains a use after free vulnerability in libavcodec/mjpegdec.c that allows attackers to trigger freed buffer reads by sending a SOF marker without a preceding SOI. Attackers can supply crafted MJPEG streams causing ff_mjpeg_decode_sof() to pass a stale raw_image_buffer pointer to hwaccel decoders like NVDEC, crashing applications or leaking heap contents.
