CVE-2026-75143
FFmpeg before commit 1c10bcc contains a heap buffer overflow in the RIST protocol reader libavformat/librist.c. libristread ignored its size argument and copied the full received payload length into the caller-provided destination buffer, overflowing it when the payload exceeds the destination...
CVE-2026-75141
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...
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...

UBUNTU-CVE-2026-75145
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...

CVE-2026-75147
FFmpeg before commit 983dae9 contains an out-of-bounds read in the AV1 RTP packetizer libavformat/rtpencav1.c. The keyframe detection loop that searches for a sequence header OBU advanced its pointer and remaining-size counter by the encoded header length plus the OBU payload size without first...

UBUNTU-CVE-2026-75146
FFmpeg before commit 65b0dab contains an out-of-bounds read in the DASH demuxer libavformat/dashdec.c. When a live DASH manifest is refreshed with a startNumber that is lower than the previous value, the current sequence number is driven negative. The fragment retrieval function checked only the...

CVE-2026-64832
A flaw was found in FFmpeg, specifically within the NVIDIA NVDEC hardware decoder. A remote attacker could exploit this double-free vulnerability by providing a specially crafted video file. This can lead to memory corruption, potentially allowing for arbitrary code execution or causing a denial ...
CVE-2026-70628
A flaw was found in FFmpeg. An attacker could exploit a signed integer overflow vulnerability within the DVB subtitle parser by providing a specially crafted WTV Windows Recorded TV Show file. This overflow can lead to a heap buffer overflow, enabling out-of-bounds memory writes. The consequence ...
