## Overview

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

wifi: ath11k: rely on mac80211 debugfs handling for vif

mac80211 started to delete debugfs entries in certain cases, causing a
ath11k to crash when it tried to delete the entries later. Fix this by
relying on mac80211 to delete the entries when appropriate and adding
them from the vif_add_debugfs handler.

## Affected

- `linux_kernel >= 6.7, < 6.7.3`
- `linux_kernel = 6.8`

## Remediation

Upgrade past the affected range:

- `linux_kernel 6.7.3`
