RHEL 10 / 9 : Red Hat Edge Manager Version 1.1.4 Security Update (Important) (RHSA-2026:68334)

high Nessus Plugin ID 346432

Synopsis

The remote Red Hat host is missing one or more security updates.

Description

The remote Redhat Enterprise Linux 10 / 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2026:68334 advisory.

Red Hat Edge Manager (RHEM) provides simple, scalable, and security-focused management of edge devices and applications. It supports image-mode RHEL and container workloads that run on Podman/Docker or Kubernetes.

RHEM is now available as a standalone feature, providing greater flexibility for edge deployments. In addition to the standalone version, RHEM continues to be offered as a plugin for the following platforms:

Red Hat Advanced Cluster Management (RHACM): Extends fleet management to edge devices.
Red Hat Ansible Automation Platform (AAP): Integrates edge management with Ansible automation.

This integration enables organizations to optimize the management and orchestration of their fleets of edge devices; whether its thousands of dispersed retail point-of-sale systems or industrial machinery on remote factory floors.

Value for customers and partners:

* This solution not only helps customers manage thousands of devices but helps scale operations.
* To manage large-scale deployments, customers need to be able to integrate with their existing management systems, support remote configuration and over-the-air updates, and collect telemetry data for advanced analytics.
* Red Hat Edge Manager offers a simple and security-focused lifecycle management, from onboarding to decommissioning of edge devices.

This complete end-to-end solution empowers organizations to gain the most value from the fleets of devices that generate data, all from a centralized location.
