## Overview

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

wifi: cfg80211: enforce HE/EHT cap/oper consistency

Xiang Mei reports that mac80211 could crash if eht_cap is set
but eht_oper isn't. Rather than fixing that for the individual
user(s), enforce that both HE/EHT have consistent elements.

## Affected

- `linux_kernel >= 6.16, < 7.0.13`
- `linux_kernel = 7.1`

## Remediation

Upgrade past the affected range:

- `linux_kernel 7.0.13`
