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.
