FFmpeg through 9.0.2 contains an out-of-bounds read vulnerability in bitpacked_decode_uyvy422() in libavcodec/bitpacked_dec.c because it never verifies packets hold width * height * 2 bytes. Attackers can supply truncated bitpacked UYVY422 packets via crafted SDP/RFC 4175 RTP sessions or raw input to crash applications or expose adjacent heap memory.
