CVE-2026-75142

Name of the Vulnerable Software and Affected Versions FFmpeg versions prior to commit 9d786e4

Description A stack buffer overflow exists in the MPEG-PS muxer within the libavformat/mpegenc.c file. This occurs when the software processes input containing more streams than the muxer's fixed-size stack buffer can accommodate. A specially crafted input with an excessive number of streams can trigger this overflow during the MPEG-PS muxing process.

Recommendations Update FFmpeg to commit 9d786e4 or a later version.
