In lib/ofp-util.c in Open vSwitch (OvS) before 2.8.1, there are multiple
memory leaks while parsing malformed OpenFlow group mod messages. NOTE: the
vendor disputes the relevance of this report, stating “it can only be
triggered by an OpenFlow controller, but OpenFlow controllers have much
more direct and powerful ways to force Open vSwitch to allocate memory,
such as by inserting flows into the flow table.”
