NVD description
FFmpeg through 9.0.2 contains an uninitialized memory use vulnerability in roq_dpcm_encode_frame() in libavcodec/roqaudioenc.c that encodes stale heap contents when flushed early. Attackers can supply short audio streams under eight frames for RoQ DPCM transcoding, causing DPCM-quantized uninitialized heap data from frame_buffer to leak into output packets.
