## Overview

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

wifi: mac80211: check/clear fast rx for non-4addr sta VLAN changes

When moving a station out of a VLAN and deleting the VLAN afterwards, the
fast_rx entry still holds a pointer to the VLAN's netdev, which can cause
use-after-free bugs. Fix this by immediately calling ieee80211_check_fast_rx
after the VLAN change.

## Affected

- `linux_kernel >= 4.14.232, < 4.15`
- `linux_kernel >= 4.19.189, < 4.19.312`
- `linux_kernel >= 5.4.114, < 5.4.274`
- `linux_kernel >= 5.10.32, < 5.10.215`
- `linux_kernel >= 5.11.16, < 5.12`
- `linux_kernel >= 5.12.1, < 5.15.154`
- `linux_kernel >= 5.16, < 6.1.84`
- `linux_kernel >= 6.2, < 6.6.24`
- `linux_kernel >= 6.7, < 6.7.12`
- `linux_kernel >= 6.8, < 6.8.3`
- `linux_kernel = 5.12`
- `linux_kernel = 6.9`
- `debian_linux = 10.0`

## Remediation

Upgrade past the affected range:

- `linux_kernel 6.8.3`
