Vulnerability description

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to insufficient validation of user-supplied input in kube-apiserver that could allow Node updates to bypass a Validating Admission Webhook. An authenticated user could exploit this by modifying Node properties to values that should have been prevented by registered admission webhooks.
