Note: Versions mentioned in the description apply only to the upstream python3-ovs3 package and not the python3-ovs3 package as distributed by SLES. See How to fix? for SLES:15.5 relevant fixed versions and status.

A flaw was found in OVN (Open Virtual Network). A remote attacker, by sending crafted DHCPv6 (Dynamic Host Configuration Protocol for IPv6) SOLICIT packets with an inflated Client ID length, could cause the ovn-controller to read beyond the bounds of a packet. This out-of-bounds read can lead to the disclosure of sensitive information stored in heap memory, which is then returned to the attacker's virtual machine port.
