Created kernel tracking bugs for this issue:

Affects: fedora-all [bug 2261906]

Comment 5 Alex 2024-03-19 15:39:13 UTC

Assuming that fixed by the https://github.com/torvalds/linux/commit/2e07e8348ea454615e268222ae3fc240421be768
(based on cmt from the RHEL-23289 ).

Maybe can close as duplicate of the CVE-2023-51779 (not sure yet, so not closing now).
