title: Ovn: insufficient validation of bfd packets may lead to denial of service
description: A flaw was found in the Open Virtual Network (OVN). In OVN clusters where BFD is used between hypervisors for high availability, an attacker can inject specially crafted BFD packets from inside unprivileged workloads, including virtual machines or containers, that can trigger a denial of service.
