Overview

KB5050048 is a Monthly Rollup update for Windows Server 2012 R2, released on January 14, 2025. This update is part of Microsoft's Extended Security Updates (ESU) program, which provides critical security updates for systems that have reached their end of support. Windows Server 2012 R2 officially reached its end of support on October 10, 2023, but organizations can continue to receive security updates through the ESU program until October 13, 2026. This update includes important security improvements and fixes to enhance the overall security posture of the operating system, particularly against vulnerabilities that could be exploited by attackers.

The update specifically addresses vulnerabilities related to the Windows Kernel Vulnerable Driver Blocklist, which is crucial for protecting systems from Bring Your Own Vulnerable Driver (BYOVD) attacks. The update is designed to ensure that systems remain secure and compliant with the latest security standards, especially for organizations that are still operating on Windows Server 2012 R2.
