What To Validate Now
- Inventory. Locate RHEL 9 OpenTelemetry Collector packages; 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 entitled RHEL 9 OpenTelemetry Collector packages branches and package or image relationships identified by RHSA-2026:76744; compare installed NEVRAs or digests with the fixed content. Do not infer applicability from product family, CVSS, or Internet reachability alone.
- Remediate. Apply opentelemetry-collector 0.158.0-1.el9_8 and the matching advisory-listed packages through the authority-supported channel and follow the current advisory.
- Validate. Confirm the resulting OpenTelemetry Collector 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

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.
