Title

ima: return error early if file xattr cannot be changed

Summary

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.

Vulnerability from github – Published: 2026-10-23 12:31 – Updated: 2026-10-23 12:31

Details

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.
