Red Hat Security Advisory: Red Hat Web Terminal Operator 1.15.1 release.
Description
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.

Technical Analysis
This advisory covers a denial of service vulnerability (CVE-2026-27145) in the golang crypto/x509 package caused by excessive processing of DNS Subject Alternative Name (SAN) entries. The issue can lead to denial of service conditions. The vulnerability affects Go versions prior to 1.26.4 and is addressed by updating to version 1.26.4 or later. The Red Hat advisory also references a related denial of service vulnerability in the net package (CVE-2026-33811). The update is available for Red Hat Enterprise Linux 10 and associated toolsets and products that bundle the affected Go packages.
Potential Impact
The vulnerability allows an attacker to cause denial of service by triggering excessive processing of DNS SAN entries in the crypto/x509 package. This can lead to resource exhaustion or application unavailability. There is no indication of confidentiality or integrity impact. No known exploits in the wild have been reported.
Mitigation Recommendations
An official fix is available from Red Hat. Users should apply the security update that upgrades golang packages to version 1.26.4 or later as provided in Red Hat Enterprise Linux 10 updates. Refer to Red Hat advisory RHSA-2026:35832 for detailed update instructions. No additional mitigation steps are required beyond applying the vendor-provided patch.
