Description
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.
Affected configurations
• linux linux kernel (>= 6.6 < 6.6.128)
• linux linux kernel (>= 6.7 < 6.12.75)
• linux linux kernel (>= 6.13 < 6.18.16)
• linux linux kernel (>= 6.19 < 6.19.6)
