Comment 1 Guilherme de Almeida Suckevicz 2022-05-30 19:08:06 UTC 
Created kernel tracking bugs for this issue:

Affects: fedora-all [bug 2091705]
Comment 2 Justin M. Forbes 2022-06-01 21:36:05 UTC 
This was fixed for Fedora years ago in the 4.20 kernel rebases.
Comment 12 Wade Mealing 2022-09-08 06:56:39 UTC 
RHEL 8 based products are not marked as affected, this was fixed in 8.4 and this flaw doesn't qualify for z stream inclusion.
