* To allow the userspace proxy to work correctly on multi-interface hosts when using the non-default-route interface, you may now set the `bindAddress` configuration option to an IP address assigned to a network interface.  The proxy will use that IP address for any required NAT operations instead of the IP address of the interface which has the default route.

A security issue was discovered in Kubernetes that could allow  Windows workloads to run as `ContainerAdministrator` even when those workloads set the `runAsNonRoot` option to `true `.

This issue has been rated low and assigned CVE-2021-25749

### Am I vulnerable?

All Kubernetes clusters with following versions, running Windows workloads with `runAsNonRoot` are impacted

#### Affected Versions

- kubelet v1.20 - v1.21
