Actually you forget the zeroth rule - don't connect stuff in the first place.
If this is a network stack fault it could be exploitable before any IP style firewall/filter. Its more of a wakeup call, for those sleeping for a 100 years after eating the poison apple, that if you have connectivity you need an active patching/update system and some focus on security to make it happen without users having to do anything, As another commentard pointed out, that alone is also a risk.
