Potential etcd data inconsistency issue in OCP 4.9 and 4.10

Issue

• Red Hat has become aware of a potential data inconsistency issue present in etcd 3.5.0-3.5.2.
• OpenShift Container Platform (OCP) versions 4.9.0 through 4.9.32 and 4.10.0 through 4.10.12 utilize the affected versions of etcd.
• The following questions may arise due to this:
  1. What should I do until a fix has been delivered?
  2. We have upgraded from 4.8 to 4.9. Are we at risk of any etcd problems?
  3. Does my cluster have inconsistent etcd data?
  4. Are 4.9.z, 4.9 to 4.10, or 4.10.z updates impacted by this?
