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.

OpenShift API for Data Protection (OADP) enables you to back up and restore application resources, persistent volume data, and internal container images to external backup storage. OADP enables both file system-based and snapshot-based backups for persistent volumes.

Multiple security vulnerabilities affecting the cosign tool and related Go cryptography libraries have been identified and fixed. These include issues parsing HTML files, a memory-safety vulnerability, and multiple issues in golang.org/x/crypto/ssh. The vulnerabilities have been addressed in updated versions provided by SUSE and Red Hat. A patch is available to remediate these issues.

This security update for Apptainer addresses multiple vulnerabilities, including CVE-2024-45310 and several CVE-2026 series issues. The update includes fixes for at least 13 CVEs and updates dependencies such as golang.org/x/crypto and golang.org/x/net to newer versions. The update also integrates vulnchecker optionally into the build process and synchronizes with the Factory version to ensure comprehensive vulnerability mitigation.

CVE-2026-39834 is a critical integer overflow vulnerability in the golang.org/x/crypto/ssh package. It occurs when writing data larger than 4GB in a single Write call on an SSH channel, causing an integer overflow in the internal payload size calculation. This overflow results in an infinite loop that sends empty packets without progress, leading to a denial of service condition. The issue stems from using a truncated integer type for size comparison, which has been addressed by switching to int64 to prevent overflow.

This update for docker-compose fixes the following issues: - CVE-2025-47913: golang.org/x/crypto/ssh/agent: client process termination when receiving an unexpected message type in response to a key listing or signing request (bsc#1253584). - CVE-2025-47914: golang.org/x/crypto/ssh/agent: non validated message size can cause a panic due to an out of bounds read (bsc#1254041). - CVE-2025-62725: OCI compose artifacts can be used to escape the cache directory and overwrite arbitrary files (bsc#1252752).

The podman tool manages pods, container images, and containers. It is part of the libpod library, which is for applications that use container pods. Container pods is a concept in Kubernetes.
