Description OSIDB Bzimport 2026-03-17 10:02:00 UTC
In the Linux kernel, the following vulnerability has been resolved:

audit: add fchmodat2() to change attributes class

fchmodat2(), introduced in version 6.6 is currently not in the change
attribute class of audit. Calling fchmodat2() to change a file
attribute in the same fashion than chmod() or fchmodat() will bypass
audit rules such as:

-w /tmp/test -p rwa -k test_rwa

The current patch adds fchmodat2() to the change attributes class.
