That is the risk of being able to write to both Masters.
It is better to write to only one Master, and have the other one in read_only mode. Also, you could set my.cnf to bring up the Master in read_only mode. This is a nuisance, because you may have neither Master writable until you manually step in, but it is better than having replication broken and, furthermore, risk the data being terribly corrupt by duplicate keys going to both Masters.
Galera, Tungsten, Clustrix, and several others provide hands-free HA.
