## Overview

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

wifi: iwlwifi: bound aligned TLV advance in FW parser

Validate ALIGN(tlv_len, 4) against remaining parser length before
consuming bytes from the firmware image.

This avoids length underflow on malformed TLVs.

## Remediation

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