CVE-2026-75147
FFmpeg versions before commit 983dae9 have an out-of-bounds read in the AV1 RTP packetizer (libavformat/rtpenc_av1.c). A crafted OBU size causes the remaining-size counter to wrap, letting the keyframe-detection loop dereference a pointer past the packet buffer. CVSS 3.1 scores 7.1 (HIGH). No in-...

CVE-2026-75145
FFmpeg before commit b4c199c contains an integer narrowing conversion flaw in the AV1 RTP packetizer (libavformat/rtpenc_av1.c). The OBU size is cast to long before being compared against the remaining frame size. On platforms where long is 32 bits (including 64-bit Windows ), sufficiently large ...
