## Overview

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

wifi: rtl8xxxu: add cancel_work_sync() for c2hcmd_work

The workqueue might still be running, when the driver is stopped. To
avoid a use-after-free, call cancel_work_sync() in rtl8xxxu_stop().

## Affected

- `linux_kernel >= 5.5, < 5.10.214`
- `linux_kernel >= 5.11, < 5.15.153`
- `linux_kernel >= 5.16, < 6.1.83`
- `linux_kernel >= 6.2, < 6.6.23`
- `linux_kernel >= 6.7, < 6.7.11`
- `linux_kernel >= 6.8, < 6.8.2`
- `debian_linux = 10.0`

## Remediation

Upgrade past the affected range:

- `linux_kernel 6.8.2`
