Chapter 2. April 2026


Review the April 2026 updates and fixes for Red Hat Lightspeed.

2.1. Product-wide updates

Review the April 2026 product-wide updates for Red Hat Lightspeed.

2.2. Red Hat Enterprise Linux updates

Review the April 2026 updates and fixes for Red Hat Lightspeed running on RHEL systems.

2.2.1. General

Upcoming security improvements and new distribution method for insights-client

With the release of RHEL 10.2 and RHEL 9.8, the distribution method for updates to insights-core is changing. The updates will now be delivered as standard RPM packages in the official Red Hat Enterprise Linux repositories. The insights-client continues to be delivered as an RPM package. As a result of this change, the insights-client will no longer automatically update insights-core during its operation.

A new, tailored SELinux policy will additionally be deployed on systems to ensure that both the insights-client and insights-core operate strictly within a fully defined and confined SELinux security context.

For more information about this update, see the Security improvements and new distribution method for insights-client KB article.

2.2.2. Inventory

UI fixes and improvements
  • Enabled workload filtering in Inventory, allowing users to filter systems running one or more workloads.
  • Added copy-to-clipboard buttons on the System Details page for UUIDs.
  • Fixed name filtering in the system tag modal. It now applies across all result pages.
  • Ensured default and custom staleness and deletion retention settings are applied consistently across all systems.
  • Aligned the order of tabs on the System Details page with the main navigation menu.
  • Fixed visual issues with the backdrop in the Delete System modal and the Add Systems or Remove System to or from Workspace modals.
  • Fixed bulk action availability when selecting systems across all result pages.
  • Resolved an issue where the System Details page did not open modals such as Packages, Processes, and others.
New Inventory experience available in Preview

The Inventory UI has been reworked to align with platform standards and to improve rendering performance. This redesign lays the groundwork for upcoming capabilities such as column management and customizable views.

Users can now try the new experience in pre-production. To enable the Preview mode in the Red Hat Hybrid Cloud Console, use the toggle at the top of the screen. Provide your feedback to help refine the experience further.

2.2.3. Advisor

Remediations from Advisor pathways
Users can now create remediation plans directly from Advisor pathways, streamlining the workflow from grouped Advisor recommendations to actionable remediation steps.

2.2.4. Vulnerability

Critical CVEs and insights for Red Hat Product Security Risk Report 2025
Red Hat Product Security’s annual Risk Report is now available, highlighting the CVEs that generated the most customer activity in the past year and the security trends observed across the ecosystem. For more information, read the Red Hat Product Security Risk Report 2025.

2.2.5. Patch / Content

Build content templates with RHEL extended update support
Users can now build Content Templates for RHEL EUS, E4S, and EEUS release streams. This extends content management capabilities to legacy environments, enabling tighter control over repositories and packages for systems running versions prior to RHEL 8.

2.2.6. Image Builder

Build bootable images for image mode RHEL
You can now use immutable systems by building bootable images for image mode RHEL deployment across the public cloud providers, including Amazon Web Services (AWS), Microsoft Azure, and Google Cloud, as well as on-premise environments using qcow2 and ISO formats. You can explore the image mode deployment model, become familiar with container technologies, and streamline management of image-based RHEL systems.
Build images with content templates for consistency from build through patching

By combining image blueprints with Content Templates, users now can create a consistent RHEL environment from image build through deployment and ongoing management.

A Content Template defines the repositories and packages that make up your standard operating environment (SOE). Associating a Content Template with an image blueprint ensures repeatable builds of an image by restricting image creation to approved repositories and packages. Systems deployed from those images remain aligned to the same content set.

When updates to the SOE are required, you can update the Content Template, rebuild the image, and apply updates consistently across deployed systems.

For more information about Content Templates, see Managing content templates.

Build images with AI acceleration drivers and additional add-on software

Image Builder now supports the inclusion of packages and drivers from add-on repositories, enabling users to build RHEL images optimized for AI hardware acceleration without requiring manual post-deployment configuration.

Supported repositories:

  • Supplementary
  • Extensions
  • CodeReady Linux Builder
  • High Availability
  • SAP Solutions
  • SAP NetWeaver

This enhancement streamlines deployment workflows for AI-enabled systems and other specialized workloads.

UI enhancements for image blueprint creation wizard
The redesigned image blueprint creation wizard provides improved guidance for image customization with a simplified workflow and fewer navigation steps. Longer, scrollable customization pages help reduce click-next fatigue and improve the overall image creation experience.

2.2.7. Malware Detection

Increased malware coverage with CrowdStrike integration

Malware Detection in Red Hat Lightspeed now integrates with CrowdStrike, expanding malware coverage for RHEL scans.

Users can now use over 2400 CrowdStrike malware signatures with existing IBM X-Force intelligence, providing broader threat detection coverage and a unified view of findings directly in the Red Hat Lightspeed console.

For more information, see Integrating Red Hat Lightspeed with CrowdStrike for enhanced malware detection coverage.

2.3. OpenShift Container Platform updates

Review the April 2026 updates and fixes for Red Hat Lightspeed services on OpenShift Container Platform clusters.

2.3.1. Advisor

Pen Drive powered by Red Hat Lightspeed

Pen Drive is a disconnected variant of OCP Advisor, and is available as a Technology Preview. It now includes kube-compare functionality for template-based cluster drift validation in a Knative-native workflow.

This enhancement expands the existing disconnected cluster checking capabilities that were originally developed in collaboration with Nokia.

For more information about Pen Drive, see Pen Drive powered by Red Hat Lightspeed.
