Descriptions

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.

En el kernel de Linux, se resolvió la siguiente vulnerabilidad: wifi: wfx: corrige la posible desreferencia del puntero NULL en wfx_set_mfp_ap() Dado que 'ieee80211_beacon_get()' puede devolver NULL, 'wfx_set_mfp_ap()' debe verificar el valor de retorno antes de examinar los datos de skb. Así que convierta este último para que devuelva un código de error apropiado y propáguelo para que regrese también desde 'wfx_start_ap()'. Compilación probada únicamente.
