## Overview

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

block: handle nogenerate/noverify properly in fs-integrity

Check the BIP_CHECK flags before generating or verifying PI information,
otherwise this can be incorrectly called for non-PI metadata and
cause generation of incorrect metadata and crashed in the verification
handler.

The new behavior matches that of the block layer auto-generated
metadata.

## Remediation

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