Description
In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
audit: add fchmodat2() to change attributes class<br />
<br />
fchmodat2(), introduced in version 6.6 is currently not in the change<br />
attribute class of audit. Calling fchmodat2() to change a file<br />
attribute in the same fashion than chmod() or fchmodat() will bypass<br />
audit rules such as:<br />
<br />
-w /tmp/test -p rwa -k test_rwa<br />
<br />
The current patch adds fchmodat2() to the change attributes class.
