CVE-2023-52593

Summary

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.
