CVE-2026-75144

FFmpeg before commit 1cdeb3c contains a heap buffer overflow vulnerability in the VC-2/Dirac RTP packetizer libavformat/rtpencvc2hq.c that allows attackers to trigger memory corruption by supplying a crafted Dirac data unit. The packetizer copies an input-derived data unit or fragment size into a...

CVE-2026-75142

FFmpeg before commit 9d786e4 contains a stack buffer overflow in the MPEG-PS muxer libavformat/mpegenc.c. When muxing input with more streams than the muxer's fixed-size stack buffer accommodates, the buffer is overflowed. A crafted input with an excessive number of streams triggers the overflow...

CVE-2026-75141

FFmpeg versions before commit acf5d7c have a heap buffer overflow in the hvcC box writer. A crafted HEVC file triggers NAL unit count overflow during muxing, leading to memory corruption; CVSS 3.1 scores it HIGH (7.8). No exploitation is confirmed. Upgrade to a version containing the fix commit. ...

CVE-2026-75141 FFmpeg Heap Buffer Overflow in hvcC Box Writer via HEVC Muxing

FFmpeg before commit acf5d7c contains a heap buffer overflow in the hvcC box writer. When writing an HEVC configuration record with more NAL units of a single type than the count field can represent, the NAL unit count overflows, causing a heap buffer overflow. A crafted HEVC input file triggers...
