Vulnerability from fkie_nvd - Published: 2026-03-17 10:16 - Updated: 2026-06-17 10:21
Severity
Summary
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.
