## Overview

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

wifi: cfg80211: check A-MSDU format more carefully

If it looks like there's another subframe in the A-MSDU
but the header isn't fully there, we can end up reading
data out of bounds, only to discard later. Make this a
bit more careful and check if the subframe header can
even be present.

## Affected

- `debian_linux = 11.0`
- `linux_kernel >= 6.3, < 6.6.27`
- `linux_kernel >= 6.7, < 6.8.6`

## Remediation

Upgrade past the affected range:

- `linux_kernel 6.8.6`
