## Overview

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

wifi: iwlwifi: fix potential use after free in iwl_mld_remove_link()

This code frees "link" by calling kfree_rcu(link, rcu_head) and then it
dereferences "link" to get the "link->fw_id".  Save the "link->fw_id"
first to avoid a potential use after free.

## Remediation

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