What Changed
Red Hat released rpm-sequoia 1.10.2.1 packages for CVE-2026-42784 on supported RHEL 9 and RHEL 10 branches.
What To Validate Now
- Inventory. Locate Red Hat Enterprise Linux 9 and 10 rpm-sequoia packages; record the installed build or digest, repository and entitlement, owner, exposure, dependencies, and maintenance group.
- Establish applicability. Compare each deployment with the product and fixed-status relationships in RHSA-2026:76734 and RHSA-2026:76733. Do not infer applicability from a component name or CVSS rating alone.
- Remediate. Apply rpm-sequoia 1.10.2.1-1.el9_8 or 1.10.2.1-1.el10_2 from the supported Red Hat channel for the exact product branch or architecture.
- Validate. Confirm the resulting package version or immutable digest, exercise representative rpm-sequoia services 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
Validate package signature verification, repository metadata, offline workflows, automated build systems, and rollback before promotion. Preserve pre-change versions or digests, logs, installation output, 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.
