Created kernel tracking bugs for this issue:

Affects: fedora-all [bug 2273120]

Comment 5 Eric Sandeen 2024-04-09 20:24:46 UTC

For future reference, we don't ship nilfs2 in RHEL. No nilfs2 issues will ever affect rhel8 or rhel9. Linked issues have been closed NOTABUG.

The result of automatic check (that is developed by Alexander Larkin) for this CVE-2024-26697 is: 	SKIP	No affected files built, so skip this CVE	NO			-	-	unknown (where first YES/NO value means if related sources built).
