nl80211_nan_add_func() does not check if the required attribute NL80211_NAN_FUNC_FOLLOW_UP_DEST is present when processing NL80211_CMD_ADD_NAN_FUNCTION request. This request can be issued by users with CAP_NET_ADMIN privilege and may result in NULL dereference and a system crash. Add a check for the required attribute presence.
Applied, thanks. johannes
