## Overview

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

wifi: ath6kl: avoid buffer overreads in WMI event handlers

The following WMI event handlers currently read from the event buffer
without first verifying that the message was large enough to hold the
expected event:
ath6kl_wmi_scan_complete_rx()
ath6kl_wmi_addba_req_event_rx()
ath6kl_wmi_delba_req_event_rx()

Add length checks to prevent overread.

## Remediation

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