What Changed

Red Hat released RHSA-2026:96091 for RHEL 9.6 Extended Update Support, addressing SMB client, IPC identifier, UDP tunnel and TUN receive-headroom flaws. The update provides the distribution packages listed below; keep the Red Hat release and support channel matched during remediation.

What To Validate Now

  1. Inventory. Record running kernel builds, architecture, kpatch state and the exact supported SAP or EUS package channel.
  2. Establish applicability. RHEL 9.6 Extended Update Support: installations of the kernel live patches packages requiring RHSA-2026:96091. Match the full installed RPM, architecture and repository to the vendor product tree; a universal upstream version range is not stated.
  3. Remediate. Apply RHSA-2026:96091 through the entitled Red Hat repositories. The fixed source builds are kpatch-patch-5_14_0-570_116_1-0:1-13.el9_6; kpatch-patch-5_14_0-570_135_1-0:1-4.el9_6; kpatch-patch-5_14_0-570_39_1-0:1-19.el9_6; kpatch-patch-5_14_0-570_66_1-0:1-18.el9_6; kpatch-patch-5_14_0-570_94_1-0:1-16.el9_6. Install the matching binary packages for the supported stream and architecture.
  4. Validate. Verify that the matching patch module is loaded for the running kernel, inspect kpatch status and service health, and retain kernel, package and module evidence.
  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

The patch packages target specific kernel builds. Match the complete kernel and package suffixes in the vendor matrix; installing a package alone does not prove the running kernel is patched. Keep the supported kernel lifecycle and reboot plan.

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.
