### Bug or Regression

- Do not add nodes labeled with kubernetes.azure.com/managed=false to backend pool of load balancer. ([#93034](https://github.com/kubernetes/kubernetes/pull/93034), [@matthias50](https://github.com/matthias50)) [SIG Cloud Provider]

- Fixed a bug that Pods could stuck in the unschedulable pod pool 
  if they're rejected by PreEnqueue plugins that could change its result by a change in resources apart from Pods.
  
  DRA plugin is the only plugin that meets the criteria of the bug in in-tree, 

**Fixed Versions**:
  - kube-apiserver v1.25.4
  - kube-apiserver v1.24.8
  - kube-apiserver v1.23.14
  - kube-apiserver v1.22.16

This vulnerability was reported by Yuval Avrahami of Palo Alto Networks
