Technical description

In the Linux kernel, the following vulnerability has been resolved:

audit: add missing syscalls to read class

The "at" variant of getxattr() and listxattr() are missing from the

audit read class. Calling getxattrat() or listxattrat() on a file to

read its extended attributes will bypass audit rules such as:

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

The current patch adds missing syscalls to the audit read class.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
