Comment 2 Ben Beasley 2022-04-08 14:28:19 UTC

https://nvd.nist.gov/vuln/detail/CVE-2022-0544
https://developer.blender.org/T94661

Based on upstream git, the fix is included in 3.1.0 and later releases (F35, F36, F37), and in 2.93.8 final (F34), so it appears that this is already resolved in current Fedora releases.
