- kube-apiserver: the `NodeRestriction` admission plugin now prevents kubelets from modifying `Node` labels prefixed with `node-restriction.kubernetes.io/`. The `node-restriction.kubernetes.io/` label prefix is reserved for cluster administrators to use for labeling `Node` objects to target workloads to nodes in a way that kubelets cannot modify or spoof.

* Scheduler only activates unschedulable pods if node's scheduling related properties change. ([#71551](https://github.com/kubernetes/kubernetes/pull/71551), [@mlmhl](https://github.com/mlmhl))
* fix issue: vm sku restriction policy does not work in azure disk attach/detach ([#71941](https://github.com/kubernetes/kubernetes/pull/71941), [@andyzhangx](https://github.com/andyzhangx))

### Detection

Kubernetes Audit logs may indicate if the user name was misspelled to bypass the restriction placed on which user is a pod allowed to run as.

If you find evidence that this vulnerability has been exploited, please contact ******@****.***

 - Selector mutation is disabled for all kinds in the
 app/v1beta2 group version, because the controllers in the workloads API do not handle
 selector mutation in
 a consistent way. This restriction may be lifted in the future, but
 it is likely that that selectors will remain immutable after the move to v1.
 You can continue to use code that depends on mutable selectors by calling
