| CRE-2025-0027 Low Impact: 7/10 Mitigation: 2/10 | Neutron Open Virtual Network (OVN) and Virtual Interface (VIF) allows port binding to dead agents, causing VIF plug timeouts | In OpenStack deployments using Neutron with the OVN ML2 driver, ports could be bound to agents that were not alive. This behavior led to virtual machines experiencing network interface plug timeouts during provisioning, as the port binding would not complete successfully. | Networking Problems | neutron | NeutronOvnTimeoutNetworkingOpenstackKnown IssuePublic |
| CRE-2025-0040 Low Impact: 6/10 Mitigation: 4/10 | Neutron Open Virtual Network (OVN) fails to bind logical switch due to race condition during load balancer creation | During load balancer creation or other operations involving logical router and logical switch associations, Neutron OVN may raise a `RowNotFound` exception when attempting to reference a logical switch that has just been deleted. This leads to a port binding failure and a rollback of the affected operation. | Networking Problems | neutron | NeutronOvnOpenstackLoad BalancerLogical SwitchOvsdbKnown IssuePublic |
