## Overview

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

pnfs/flexfiles: Fix memory leak in nfs4_ff_alloc_deviceid_node()

In nfs4_ff_alloc_deviceid_node(), if the allocation for ds_versions fails,
the function jumps to the out_scratch label without freeing the already
allocated dsaddrs list, leading to a memory leak.

Fix this by jumping to the out_err_drain_dsaddrs label, which properly
frees the dsaddrs list before cleaning up other resources.

## Remediation

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