What Changed

Red Hat released PostgreSQL security content with supported branch-specific fixed packages or images for the listed CVEs.

What To Validate Now

  1. Inventory. Locate PostgreSQL 15 and 16 packages for supported RHEL 8, 9, and 10 streams deployments, versions, enabled features, exposure paths, owners, and dependent services.
  2. Establish applicability. Compare each deployment with the authority's affected-version statement: The exact entitled PostgreSQL 15 and 16 packages for supported RHEL 8, 9, and 10 streams builds before the branch-specific package, image, or digest listed by Red Hat. Do not infer applicability from product family or severity alone.
  3. Remediate. Apply PostgreSQL 15.19 and 16.15 with the advisory-listed RHEL module and package builds through the supported vendor or project channel, following the current advisory and change-control requirements.
  4. Validate. Confirm the resulting version or managed-service state, exercise representative functionality and recovery paths, monitor for regressions, and document exceptions.
  5. 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

Use the exact supported release stream and repository. Test dependencies, clusters, integrations, and rollback before broad deployment; a CVSS rating or reachable feature is not evidence of exploitation.

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.
