### API Change

- Added error handling for seccomp localhost configurations that do not properly set a localhostProfile ([#117020](https://github.com/kubernetes/kubernetes/pull/117020), [@cji](https://github.com/cji)) [SIG API Machinery and Node]

  @Throws(SocketException::class)
  override fun getKeepAlive(): Boolean = delegate!!.keepAlive

  override fun getLocalAddress(): InetAddress = delegate!!.localAddress

  override fun getLocalPort(): Int = delegate!!.localPort

  @Throws(IOException::class)
  override fun getOutputStream(): OutputStream = delegate!!.outputStream

  override fun getPort(): Int = delegate!!.port

  @Throws(SocketException::class)

- Added a warning that TLS 1.3 ciphers are not configurable. ([#115399](https://github.com/kubernetes/kubernetes/pull/115399), [@3u13r](https://github.com/3u13r)) [SIG API Machinery and Node]
- Added error handling for seccomp localhost configurations that do not properly set a `localhostProfile`. ([#117020](https://github.com/kubernetes/kubernetes/pull/117020), [@cji](https://github.com/cji))

The merged fix enforces validation against the proxying address for a Node. In some cases, the fix can break clients that depend on the `nodes/proxy` subresource, specifically if a kubelet advertises a localhost or link-local address to the Kubernetes control plane. Configuring an egress proxy for egress to the cluster network can also mitigate this vulnerability.

**Affected Versions**:
  - kube-apiserver v1.25.0 - v1.25.3

    * Keep in mind that this callback URL is independent of whichever one is used by your frontend. You might also have another callback at `https://yourdomain.com/login/callback`.
