GHSA-W2J5-3RCX-VX7X Sysctls applied to containers with host IPC or host network namespaces can affect the host

Impact Before setting the sysctls for a pod, the pods namespaces must be unshared created. However, in cases where the pod is using a host network or IPC namespace, a bug in CRI-O caused the namespace creating tool pinns to configure the sysctls of the host. This allows a malicious user to set...
