## Overview

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

wifi: mt76: mt7921: validate CLC firmware records

The CLC region is supplied by firmware, but the loader trusts the
region count and each record length. A malformed image can make the
region table pointer precede the firmware buffer, make the record loop
fail to advance, or index phy->clc past its end. Validate the table and
record bounds before dereferencing or copying.

## Remediation

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