What To Validate Now
- Inventory. Locate curl and libcurl on RHEL 9.8 Extended Update Support deployments, versions, enabled features, exposure paths, owners, and dependent services.
- Establish applicability. Compare each deployment with the authority's affected-version statement: The entitled RHEL 9.8 EUS curl and libcurl package relationships listed by RHSA-2026:80511. Do not infer applicability from product family or severity alone.
- Remediate. Apply curl and libcurl 7.76.1-40.el9_8.8 through the supported vendor or project channel, following the current advisory and change-control requirements.
- Validate. Confirm the resulting version or managed-service state, exercise representative functionality and recovery paths, monitor for regressions, and document exceptions.
- 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
Do not substitute package builds across RHEL branches. Test curl and libcurl consumers, integrations, service restarts, and rollback before broad deployment. Preserve the authority snapshot, asset and owner records, before-and-after versions, change approval, installation output, validation results, exceptions, and rollback evidence.
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.
