Comment 1 Alex 2023-02-13 11:31:10 UTC 
Created kernel tracking bugs for this issue:

Affects: fedora-all [bug 2169344]
Comment 4 Justin M. Forbes 2023-03-01 19:27:52 UTC 
This was fixed for Fedora with the 6.1.9 stable kernel updates.
Comment 10 Alex 2023-06-28 16:44:12 UTC 
Memory allocations with the GFP_KERNEL should not be considered as CVE if alloc small amount of memory (based on
"
GFP_KERNEL - both background and direct reclaim are allowed and the default page allocator behavior is used. That means that not costly allocation requests are basically no-fail but there is no guarantee of that behavior so failures have to be checked properly by callers (e.g. OOM killer victim is allowed to fail currently).
",
and for more info see: https://lwn.net/Articles/627419/ ).

However, particular for this CVE I'm not sure if always small amount of memory request, so it is just in case as potential security issue.
