The multicluster engine for Kubernetes provides the foundational components that are necessary for the centralized management of multiple Kubernetes-based clusters across data centers, public clouds, and private clouds. You can use the engine to create new Red Hat OpenShift Container Platform clusters or to bring existing Kubernetes-based clusters under management by importing them. After the clusters are managed, you can use the APIs that are provided by the engine to distribute configuration based on placement policy.

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. Security Fixes: * flightctl: golang crypto/x509: Denial of Service via excessive processing of DNS SAN entries (CVE-2026-27145) * flightctl: Go encoding/asn1: Denial of Service via excessive recursion in Unmarshal (CVE-2026-33818) * flightctl: OpenTelemetry-Go: Denial of Service via oversized baggage headers (CVE-2026-41178) * flightctl: Billy: Denial of Service via crafted input due to insufficient validation (CVE-2026-44740) * flightctl: Arc: Information disclosure and Denial of Service via unauthenticated debug endpoints (CVE-2026-48050) * flightctl: golang.org/x/text: Denial of Service via invalid UTF-8 input (CVE-2026-56852) * flightctl: Go net/http: Unencrypted HTTP/2 connections vulnerable to Denial of Service (CVE-2026-56853) * flightctl: Go html/template: Cross-Site Scripting via pathological input (CVE-2026-56858) * flightctl: Go: Denial of Service via XML decoding recursion depth issue (CVE-2026-56859) * flightctl: golang net/url: Denial of Service from quadratic complexity in path resolution (CVE-2026-56860) * flightctl: Golang crypto/tls: Denial of Service via indefinite KeyUpdate messages (CVE-2026-56862) * flightctl: go-git: Arbitrary file read/write via symbolic link resolution (CVE-2026-71556)

iskorotkov/avro is a fast Go Avro codec. Prior to 2.33.0, the Avro array and map decoders looped over an attacker-controlled block-count value without checking the underlying reader's error state inside the loop body. Reader.ReadBlockHeader returns the count as a Go int, which is 64-bit on amd64 / arm64 targets — so a producer can declare a block of up to math.MaxInt64 (~9.2 × 10¹⁸) elements followed by EOF (or any truncated payload), and the decoder will attempt that many no-op iterations before propagating the error. The realistic ceiling is "indefinite until the worker is killed externally" — a single hostile payload pins a CPU core until the process is OOM-killed, deadline-cancelled, or terminated. Remote, unauthenticated denial-of-service. This vulnerability is fixed in 2.33.0.
