About this tag
Kernel driver security on Windows covers the trust mechanisms, signing policies, and compatibility challenges that affect how kernel-mode drivers are loaded and executed. Recent discussions highlight Microsoft's planned April 2026 change to stop loading legacy cross-signed drivers by default, while maintaining an allow list and evaluation mode for enterprise testing. Another topic involves Electronic Arts developing a native ARM64 kernel driver for its Javelin anticheat system to support Windows on Arm and future Linux/Proton compatibility. Additionally, a Windows 11 cumulative update (KB5074109) caused boot failures linked to driver-related issues, requiring recovery via WinRE. These threads illustrate the ongoing tension between security hardening, hardware diversity, and system stability in the Windows kernel driver ecosystem.
