Senserva AI Opinion for CVE-2026-32220

A further UEFI Secure Boot bypass, this one covers Windows 11 26H1 and Windows Server 2025 Core at CVSS 9.8 and 64 percent EPSS, extending the firmware-trust concern to current builds. Secure Boot bypasses matter because they open the door to bootkits that persist beneath the operating system. With multiple Secure Boot flaws this cycle, newer systems are not exempt.

Do this: Apply the update to Windows 11 26H1 and Server 2025 Core, and confirm Secure Boot stays enabled in firmware afterward.
