## Overview

An issue was discovered in the Linux kernel before 5.19.16. Attackers able to inject WLAN frames could cause a buffer overflow in the ieee80211_bss_info_update function in net/mac80211/scan.c.

## Affected

- `linux_kernel >= 5.1, < 5.4.218`
- `linux_kernel >= 5.5, < 5.10.148`
- `linux_kernel >= 5.11, < 5.15.74`
- `linux_kernel >= 5.16, < 5.19.16`
- `linux_kernel >= 6.0, < 6.0.2`
- `fedora = 35`
- `fedora = 36`
- `fedora = 37`
- `debian_linux = 10.0`
- `debian_linux = 11.0`

## Remediation

Upgrade past the affected range:

- `linux_kernel 6.0.2`
