### CVE-2023-3955: Insufficient input sanitization on Windows nodes leads to privilege escalation

* Only use the first IP address got from instance metadata. This is because Azure CNI would set up a list of IP addresses in instance metadata, while only the first one is the Node's IP. ([#71736](https://github.com/kubernetes/kubernetes/pull/71736), [@feiskyer](https://github.com/feiskyer))

  
  Additionally, the FailureTarget condition is also added to the Job object in the first Job
  status update as soon as the failure conditions are met (backoffLimit is exceeded, maxFailedIndexes, 
  or activeDeadlineSeconds is exceeded).
  
  Similarly, the SuccessCriteriaMet condition is added in the first update as soon as the expected number
  of pod completions is reached.

  using ethtool to disable checksum offload on your primary network interface, you should
