Details are scarce at the moment as more details will be published soon. But I would recommend everybody to stop using WiFi completely by disabling it at home, and not connecting to anything in public either. It seems to be a protocol level exploit, so it's not yet sure whether this can easily be patched. Stay safe, all!
"This is a core protocol-level flaw in WPA2 wi-fi and it looks bad. Possible impact: wi-fi decrypt, connection hijacking, content injection."
