### Bug or Regression

- Fix a bug that caused to panic the apiserver when trying to allocate a Service with a dynamic ClusterIP and it has been configured with Service CIDRs with a /28 mask for IPv4 and a /124 mask for IPv6 ([#115334](https://github.com/kubernetes/kubernetes/pull/115334), [@aojea](https://github.com/aojea)) [SIG Network and Testing]
