Comment 1 Fabio Valentini 2025-12-05 14:56:15 UTC 
CVE-2025-14087 appears to be the CVE that got requested for this issue in glib:
https://gitlab.gnome.org/GNOME/glib/-/issues/3834

This will be fixed in the "glib2" package in Fedora, there is no action required for Rust packages that just use glib2 via the Rust bindings.
