What Changed

Red Hat released replacement OpenSSH packages for seven vulnerabilities on the RHEL 10.0 Extended Update Support branch.

What To Validate Now

  1. Inventory. Locate Red Hat Enterprise Linux 10.0 EUS OpenSSH packages; record the installed build or digest, repository and entitlement, owner, exposure, dependencies, and maintenance group.
  2. Establish applicability. Compare each deployment with the product and fixed-status relationships in RHSA-2026:76748. Do not infer applicability from a component name or CVSS rating alone.
  3. Remediate. Apply openssh 9.9p1-7.el10_0.5 from the supported Red Hat channel for the exact product branch or architecture.
  4. Validate. Confirm the resulting package version or immutable digest, exercise representative OpenSSH services and recovery paths, monitor for regressions, and record the result.
  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

Keep an independent privileged session, validate server and client configuration, host keys, authentication, forwarding, bastions, automation, FIPS behavior, and rollback. 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.
