Impact statement for the OCPBUGS-57179 series:

Which 4.y.z to 4.y'.z' updates increase vulnerability?

• any to 4.18.z

Which types of clusters?

• A cluster gets impacted if it has assigned EgressIPs which can be verified by the PromQL query on the cluster count(ovnkube_clustermanager_num_egress_ips) > 0

What is the impact? Is it serious enough to warrant removing update recommendations?

• EgressIP functionality may fail if a pod IP is reused

How involved is remediation?

• SSH into each Node and run a command to either clear all the databases or clear the OVN constructs that are causing the issue. We recommend detection then flushing the OVN DBs. See https://access.redhat.com/solutions/7125049 for details.

Is this a regression?

• yes
