## Overview

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

HID: nintendo: fix rumble worker null pointer deref

We can dereference a null pointer trying to queue work to a destroyed
workqueue.

If the device is disconnected, nintendo_hid_remove is called, in which
the rumble_queue is destroyed. Avoid using that queue to defer rumble
work once the controller state is set to JOYCON_CTLR_STATE_REMOVED.

This eliminates the null pointer dereference.

## Affected

- `linux_kernel >= 5.16, < 5.19.7`
- `linux_kernel = 6.0`

## Remediation

Upgrade past the affected range:

- `linux_kernel 5.19.7`
