Microsoft has released a public preview of WSL Container, a built-in feature of the Windows Subsystem for Linux that lets you create, run, and manage Linux containers directly from Windows without installing Docker Desktop, Podman Desktop, or any other third-party runtime. The feature ships in two parts: a command-line tool called wslc.exe and a container API distributed as a NuGet package for C, C++, and C# developers. This article covers the installation steps, key capabilities, enterprise integration points, and current limitations you should be aware of before adopting it.

Oracle has released VirtualBox 7.2.12, a maintenance update addressing a critical stability flaw affecting Linux hosts. The most significant fix resolves a bug that caused full kernel freezes on Arch Linux when attempting to start a virtual machine. This issue previously required a hard hardware reset because the system would stop responding before any diagnostic information could be logged.

T-Mobile is currently engaged in a legal dispute with Broadcom to secure extended support for its massive VMware environment as it transitions to alternative platforms. The telecommunications giant relies on VMware software to manage over 303,000 CPU cores that host approximately 1,000 internal applications. This conflict stems from Broadcom’s decision to terminate perpetual licenses and standalone support contracts following its acquisition of the virtualization vendor.

Citrix has released urgent security updates to address six vulnerabilities in NetScaler ADC and NetScaler Gateway appliances. The most severe flaws, including CVE-2026-8451, carry a CVSS score of 8.8 and involve insufficient input validation that leads to memory overreads. These vulnerabilities primarily affect systems configured as SAML Identity Providers, a common setup for enabling single sign-on across enterprise applications.

Red Hat is positioning OpenShift as a unified platform to manage legacy virtual machines, modern containers, and GPU-intensive AI workloads under a single operational model. This consolidation aims to eliminate the inefficiencies of maintaining separate management teams and security protocols for different infrastructure types. By using a universal abstraction layer, administrators can maintain operational consistency across private data centers, public clouds, and edge environments.

Kali Linux 2026.2 introduces significant optimizations for virtual environments by removing unnecessary graphics firmware from pre-built VM images. This change reduces the initial RAM disk size from 200 MB to 60 MB, resulting in boot times that are approximately three times faster. Administrators managing virtual labs will also benefit from updated helper scripts that provide consistent commands for starting and stopping tool-based services.

Microsoft has launched the public preview of WSL containers, a feature that allows Linux containers to run natively on Windows 11 without third-party tools like Docker Desktop. This integration introduces a new command-line interface called wslc.exe, which supports familiar container commands and includes a built-in alias for container.exe. Administrators can access this preview immediately by updating to the latest pre-release version of the Windows Subsystem for Linux via the terminal.

Microsoft has released the public preview of Azure Linux 4.0, a free, Fedora-based distribution specifically optimized for Azure virtual machines and VM Scale Sets. Originally developed as an internal project called CBL-Mariner, the operating system now powers major infrastructures like LinkedIn and Databricks. Unlike general-purpose distributions, this version is a stripped-down, text-based OS designed to minimize attack surfaces by excluding graphical interfaces and unnecessary tools.
