CVE-2026-75145 FFmpeg Integer Narrowing Conversion OOB Memory Access in AV1 RTP Packetizer

FFmpeg before commit b4c199c contains an incorrect integer narrowing conversion in the AV1 RTP packetizer libavformat/rtpencav1.c. The OBU size is cast to long before comparison against the remaining frame size. On targets where long is 32 bits, including 64-bit Windows, sufficiently large OBU si...
