Description Samuele Negrini 2026-10-14 15:35:06 UTC 
Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

A vulnerability was found in libsndfile up to 1.2.2. This issue affects the function wavlike_subchunk_parse of the file src/wavlike.c of the component WAV Parsing. Performing a manipulation results in use of uninitialized variable. Remote exploitation of the attack is possible. The exploit has been made public and could be used. The project was informed of the problem early through an issue report but has not responded yet.
