Red Hat Updates python-lxml on RHEL 8 Extended Streams
Tech GuruQuick Answer
Red Hat published RHSA-2026:84592 and RHSA-2026:84593 for python-lxml on RHEL 8.6 and 8.8 extended support streams. The branch-specific packages address CVE-2026-49825 on the listed extended support streams. Match each entitled system to the exact advisory relationship, apply python-lxml 4.2.3-4.el8_6.1 or 4.2.3-4.el8_8.1 for the matching stream, validate dependent operations, and retain evidence.
Match The Entitled RHEL Stream And Apply Its Supported Package
What to do now: Inventory python-lxml on RHEL 8.6 and 8.8 extended support streams, compare installed NEVRAs and entitlements with the exact Red Hat product relationships, apply python-lxml 4.2.3-4.el8_6.1 or 4.2.3-4.el8_8.1 for the matching stream, validate dependent workloads, and preserve change evidence.

What Changed
The branch-specific packages address CVE-2026-49825 on the listed extended support streams.
What To Validate Now
- Inventory. Locate python-lxml on RHEL 8.6 and 8.8 extended support streams; record the installed NEVRA, RHEL minor stream, repository and entitlement, accountable owner, exposure, dependent workloads, and maintenance group.
- Establish applicability. Use the product-status relationships in RHSA-2026:84592 and RHSA-2026:84593. The RHEL 8.6 AUS/EUS and RHEL 8.8 SAP/TUS product relationships listed by the advisories. Do not transfer package applicability between RHEL branches.
- Remediate. Install python-lxml 4.2.3-4.el8_6.1 or 4.2.3-4.el8_8.1 for the matching stream from the supported Red Hat repository for the matching entitled branch, following the current advisory and local change controls.
- Validate. Confirm the installed NEVRA and repository, restart affected services when required, exercise representative workloads and recovery paths, monitor for regressions, and document exceptions.
- 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 package for each entitled RHEL stream. Test dependent applications and rollback before broad deployment; the advisory severity does not establish exploitation or applicability to a particular system.
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.
