## Overview

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

ima: return error early if file xattr cannot be changed

During early boot, the filesystem is read-only and any changes
to xattrs are not allowed. This fails in case of ext4 because
changing xattr starts an ext4 transaction which fails with the
following warning.

Detect the state of the file early and return the error.
