## Overview

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

mt76: mt7921: fix crash when startup fails.

If the nic fails to start, it is possible that the
reset_work has already been scheduled.  Ensure the
work item is canceled so we do not have use-after-free
crash in case cleanup is called before the work item
is executed.

This fixes crash on my x86_64 apu2 when mt7921k radio
fails to work.  Radio still fails, but OS does not
crash.

## Affected

- `linux_kernel >= 4.16, < 5.15.34`
- `linux_kernel >= 5.16, < 5.16.20`
- `linux_kernel >= 5.17, < 5.17.3`

## Remediation

Upgrade past the affected range:

- `linux_kernel 5.17.3`
