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

      4.18 to 4.19.[0-4]. The issue is fixed in 4.19.5.

      Which types of clusters?

      Hosted Control Plane (HCP/HyperShift) clusters running on AWS

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

      Kubernetes Services of type LoadBalancer may experience temporary availability disruption during node updates because health checks are not set up properly to monitor Node readiness state.

      How involved is remediation?

      The issue should resolve itself after cluster upgrade.

      Is this a regression?

      Yes, in updates from 4.18 to 4.19.0 up to 4.19.4
