CVE-2026-75144
CVE-2026-75144 is a heap buffer overflow in FFmpeg 's VC-2/Dirac RTP packetizer (libavformat/rtpenc_vc2hq.c). The packetizer copies an input-derived data unit or fragment size into a fixed-size buffer without an upper bound check, allowing memory corruption when a crafted Dirac data unit is packe...
