CVE-2023-1668
A flaw was found in openvswitch (OVS). When processing an IP packet with protocol 0 OVS will install the datapath flow without the action modifying the IP header. This issue results (for both kernel and userspace datapath) in installing a datapath flow matching all IP protocols (nw_proto is wildcarded) for this flow but with an incorrect action possibly causing incorrect handling of other IP packets with a != 0 IP protocol that matches this dp flow.
