Red Hat published supported mod_auth_openidc replacement content for the advisory-listed CVEs and product branches.
What To Validate Now
- Inventory. Locate RHEL 10 mod_auth_openidc packages; record the installed build, repository and entitlement, owner, exposure, dependencies, and maintenance group.
- Establish applicability. Compare every system with the product and package relationships in RHSA-2026:75581. Do not infer applicability from the component name or CVSS rating alone.
- Remediate. Install mod_auth_openidc 2.4.16.11-1.el10_2.1 from the supported Red Hat channel for the exact branch.
- Validate. Confirm the installed package or image digest, exercise representative mod_auth_openidc functions and recovery paths, monitor for regressions, and record 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
Test OpenID Connect login, logout, callback, session, and proxy behavior with a rollback path before broad deployment. Preserve pre-change versions, logs, installation output, validation evidence, and any rollback decision.
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.
