Comment 1 Nick Tait 2024-02-27 22:11:16 UTC 
Created kernel tracking bugs for this issue:

Affects: fedora-all [bug 2266458]
Comment 5 Justin M. Forbes 2024-02-27 22:37:04 UTC 
This was fixed for Fedora with the 5.11.17 stable kernel update.
Comment 6 Eric Sandeen 2024-02-27 23:31:14 UTC 
This was already fixed in RHEL9 before it even branched, and for RHEL8.9 via bug #2135881

If zstreams are required, the bug seems to have been introduced in RHEL8.5 via bug #1920812
Comment 8 Alex 2024-06-09 16:34:23 UTC 
The result of automatic check (that is developed by Alexander Larkin) for this CVE-2021-46922 is: CHECK	Maybe valid. Check manually. with impact LOW (that is an approximation based on flags INIT SIMPLEFIX  ; these flags parsed automatically based on patch data). Such automatic check happens only for Low/Moderates (and only when not from reporter, but parsing already existing CVE). Highs always checked manually (I check it myself and then we check it again in Remediation team). In rare cases some of the Moderates could be increased to High later.
