Microsoft WSUS Patch Breaks Hotpatching on Windows Server 2025

A recent Microsoft security update (KB5070881) aimed at fixing a critical vulnerability in the Windows Server Update Service (WSUS) inadvertently disrupted hotpatching for some Windows Server 2025 systems enrolled in the Hotpatch program. This disruption prevents affected servers from applying updates without requiring a restart, forcing administrators to revert to traditional cumulative updates until January 2026. The vulnerability, CVE-2025-59287, allowed potential remote code execution by exploiting weaknesses in WSUS. Microsoft has since released a new update (KB5070893) that addresses the vulnerability while restoring hotpatching capabilities for those who have not yet installed the problematic update.
