## Overview

In the Linux kernel 5.8 through 5.19.x before 5.19.16, local attackers able to inject WLAN frames into the mac80211 stack could cause a NULL pointer dereference denial-of-service attack against the beacon protection of P2P devices.

## Affected

- `linux_kernel >= 5.8, < 5.19.16`
- `fedora = 35`
- `fedora = 36`
- `fedora = 37`
- `debian_linux = 10.0`
- `debian_linux = 11.0`

## Remediation

Upgrade past the affected range:

- `linux_kernel 5.19.16`
