## Overview

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

ASoC: nau8821: Cancel delayed work on component remove

Attempting to unload the driver while a jack detection work is pending
would likely crash the kernel when it is eventually scheduled for
execution:

Cancel unscheduled jdet_work or wait for its execution to finish before
the component driver gets removed.

## Affected

- `linux_kernel >= 5.16, < 6.19.4`

## Remediation

Upgrade past the affected range:

- `linux_kernel 6.19.4`
