This update is part of Microsoft's ongoing commitment to provide security enhancements and reliability improvements for older operating systems that are still in use. The update addresses critical vulnerabilities and includes cumulative updates that enhance the overall performance and security of the .NET Framework.

This update specifically addresses a remote code execution vulnerability identified as CVE-2025-21176, which could potentially allow attackers to execute arbitrary code on affected systems. Additionally, it resolves a rare issue that could lead to an infinite loop when a thread first enters the Common Language Runtime (CLR).
