- Fixed a potential data race in DRA with no known real-world implications. ([#123222](https://github.com/kubernetes/kubernetes/pull/123222), [@pohly](https://github.com/pohly))
- Fixed a race condition in the iptables mode of kube-proxy in `1.27` and later
  that could result in some updates getting lost (e.g., when a service gets a
