Description

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.

Affected configurations

• linux linux kernel (< 6.1.77) • linux linux kernel (>= 6.2 < 6.6.16) • linux linux kernel (>= 6.7 < 6.7.4)
