AI-suggested
The vendor advisory does not currently provide any fixes or patches for these vulnerabilities. Users should monitor Red Hat's official channels for updates and consider mitigating exposure by limiting access to affected components or applying any recommended configuration changes once available. Since this is a self-managed on-premise deployment, vendor-managed remediation does not apply.
Description
The RHTAS Operator can be used with OpenShift Container Platform 4.15, 4.16, 4.17, 4.18 and 4.19
