Package        : openvswitch
Version        : 2.10.7+ds1-0+deb10u5
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.

For Debian 10 buster, this problem has been fixed in version
2.10.7+ds1-0+deb10u5.

We recommend that you upgrade your openvswitch packages.
