## Overview

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

nfsd: fix handling of NFSEXP_PNFS in the netlink codepath

The rework of how block layouts were checked moved the check for
NFSEXP_PNFS out of nfsd4_setup_layout_type() and into the callers. That
patch didn't account for the new call in nfsd4_setup_layout_type().

## Remediation

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