## Overview

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

f2fs: fix to clear dirty flag on folio in error path

If node block is corrupted due to chksum mismatch or inconsistent
footer info, it needs to drop clear flag of node folio, in order
to persist inconsistent node data to storage.

## Remediation

Refer to the linked advisories for vendor-supplied fixes and affected version ranges.
