### Bug or Regression

The RuntimeClass alpha feature enables a node to surface multiple runtime options to support a variety of workload types.  Examples include native linux containers, and “sandboxed” containers that isolate the container from the host kernel.

- Add --permit-address-sharing flag to `kube-apiserver` to listen with `SO_REUSEADDR`. While allowing to listen on wildcard IPs like 0.0.0.0 and specific IPs in parallel, it avoids waiting for the kernel to release socket in `TIME_WAIT` state, and hence, considerably reducing `kube-apiserver` restart times under certain conditions. ([#93861](https://github.com/kubernetes/kubernetes/pull/93861), [@sttts](https://github.com/sttts))

- Add `/sys/devices/virtual/powercap` to default masked paths. It avoids the potential security risk that the ability to read these files may offer a power-based sidechannel attack against any workloads running on the same kernel.

- Fix a bug that Pods could stuck in the unschedulable pod pool 

- Kubelet: a configuration file specified via `--config` is now loaded with strict deserialization,...

### Bug or Regression

- Bump system-validators to v1.10.2: remove version-specific cgroup kernel config checks to avoid false failures on cgroup v2 systems when v1-only configs are missing. ([#134087](https://github.com/kubernetes/kubernetes/pull/134087), [@pacoxu](https://github.com/pacoxu)) [SIG Cluster Lifecycle]
