Comment 3 John Helmert III archtester Gentoo Infrastructure gentoo-dev Security 2022-10-22 02:13:57 UTC 
OOB read in a library, very unlikely to be exploitable, no GLSA. All done!

Also, CVE requested.
Comment 4 Marko Kohtala 2023-10-20 05:48:30 UTC 
The Alias CVE appears to be wrong. Correct would be CVE-2021-46848.
