✅ Remediation

For details on how to apply this update, which includes the changes described in this advisory, refer to: https://access.redhat.com/articles/11258 The system must be rebooted for this update to take effect. Workaround: Mitigation of this issue requires restricting access to the ability to create, modify, or destroy network namespaces. By default, this ability is restricted to privileged users. However, that restriction is only applicable to the host system itself and not to containerized applications. Administrators of container hosts should ensure that only trusted accounts can run containers. Workaround: Mitigation for this issue is either not available or the currently available options don't meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
