✅ Remediation
For details on how to apply this update, which includes the changes described in this advisory, refer to: https://images.redhat.com/ Workaround: To mitigate this issue, avoid using `openvt -u` in privileged `kbrequest`/init deployments. Instead, configure the keyboard request to initiate a standard authenticated login on the new virtual terminal, or disable the keyboard request binding entirely until a fix is available. Changes to `kbrequest` configurations may require a system restart or service reload to take effect.
