FFmpeg git-master before commit d5873b was discovered to contain a memory leak in the component libavutil/mem.c.
https://access.redhat.com/security/cve/CVE-2025-25468 links to https://trac.ffmpeg.org/ticket/11415, but that is closed as invalid. Commit log for d5873b says: avformat/iamf_parse: add missing av_free() call on failure path Fixes ticket #11416 I'm going to assume this is about #11416.
Fixed in FFmpeg 7.1.1 (04fd3f69b3c3b608ca2654e3688dae7adc3adc8d). 6.1.2 and earlier are not affected as IAMF support was added in 7.0.
