# CVE-2023-52593

> 3.1 LOW

## Beschreibung

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

wifi: wfx: fix possible NULL pointer dereference in wfx_set_mfp_ap()

Since 'ieee80211_beacon_get()' can return NULL, 'wfx_set_mfp_ap()'
should check the return value before examining skb data. So convert
the latter to return an appropriate error code and propagate it to
return from 'wfx_start_ap()' as well. Compile tested only.

## Patch verfügbar (OSV)

- Kernel ≥ 6.1.77
- Kernel ≥ 6.6.16
- Kernel ≥ 6.7.4
