The Self Node Remediation Operator works in conjunction with machine health check or node health check to provide automatic remediation of unhealthy nodes by rebooting them. This minimizes downtime for stateful applications and ReadWriteOnce (RWO) Volumes, as well as restoring compute capacity in the event of transient failures.

Security Fix(es):

  • golang: net/http, x/net/http2: rapid stream resets can cause excessive work (CVE-2023-44487) (CVE-2023-39325)
