CVE ID         : CVE-2023-5366
Debian Bug     : 

A flaw was found in Open vSwitch that allows ICMPv6 Neighbor
Advertisement packets between virtual machines to bypass OpenFlow rules.
This issue may allow a local attacker to create specially crafted
packets with a modified or spoofed target IP address field that can
redirect ICMPv6 traffic to arbitrary IP addresses.

We recommend that you upgrade your openvswitch packages.
