Senserva AI Opinion for CVE-2026-32222

This Win32k escalation spans the newest builds on both sides of the fleet: Windows 11 Version 26H1 and Windows Server 2025 Server Core, rated Critical (CVSS 9.8) with a 64 percent EPSS exploit probability. Win32k exploitation techniques are among the best documented in Windows attack history, so new variants tend to move from advisory to working exploit quickly. Its presence on 26H1 and Server 2025 shows the subsystem remains a liability even in current code.

Do this: Add 26H1 clients and Server 2025 hosts to the win32k remediation sweep and verify with a scan across both.
