CVE-2026-75145

A flaw was found in FFmpeg. An incorrect integer narrowing conversion in the AV1 RTP packetizer can lead to an out-of-bounds memory access. This occurs when processing specially crafted AV1 RTP Real-time Transport Protocol packets, where a large OBU Operating Block Unit size is incorrectly handle...

CVE-2026-75147

A flaw was found in FFmpeg's AV1 Real-time Transport Protocol RTP packetizer. A local attacker could entice a user to process a crafted AV1 input packet. This crafted packet could cause an out-of-bounds read, potentially leading to information disclosure or a denial of service DoS condition...

Out-of-bounds Read

Overview Affected versions of this package are vulnerable to Out-of-bounds Read through the AV1 RTP packetizer’s ffrtpsendav1 keyframe sequence-header search loop in libavformat/rtpencav1.c. An attacker can make FFmpeg read past the end of an AV1 packet by supplying a crafted AV1 frame with an...

SUSE CVE-2026-75145

FFmpeg before commit b4c199c contains an incorrect integer narrowing conversion in the AV1 RTP packetizer libavformat/rtpencav1.c.
