What To Validate Now
- Inventory. Locate RHEL 8.4, 8.6, and 8.8 entitled mod_auth_openidc:2.3 module streams; record versions, enabled features, exposure paths, owners, dependencies, support channels, and maintenance groups.
- Establish applicability. Compare every deployment with the authority's affected statement: The exact supported RHEL 8.4, 8.6, and 8.8 entitled mod_auth_openidc:2.3 module streams builds marked affected in the advisory product-status relationships. Do not infer applicability from product family, CVSS, or Internet reachability alone.

- Validate. Confirm the resulting mod_auth_openidc build or managed state, exercise representative services and recovery paths, monitor for regressions, and retain the result.
- Retain evidence. Preserve asset and owner identifiers, the applicability decision, before-and-after versions, change approval, installation output, validation results, and any exception or rollback record.
Operational Cautions
Follow the entitled Red Hat update channel and verify package or image relationships for the exact product branch. Preserve pre-change state, installation output, logs, validation evidence, and rollback decisions.
Evidence To Retain
- Exact product, release stream, package or application version, enabled feature, environment, and accountable owner.
- UTC timestamps, authority revision, approved change record, installer or package-manager output, and resulting version.
- Relevant logs and monitoring evidence, test results, exceptions, compensating controls, and rollback decisions.
