## Overview

A flaw was found in the Linux kernel's mt7925 Wi-Fi driver. During multi-link power-save setup, the `mlo_pm_work` is queued with a delay but not properly cancelled when the device is stopped. This can lead to the work item attempting to access a deallocated workqueue, resulting in a kernel warning and potentially causing a Denial of Service (DoS) due to system instability.
