Microsoft's recent release of the KB5055612 update (OS Build 19045.5796) for Windows 10 version 22H2 brings significant improvements to the Windows Subsystem for Linux 2 (WSL2) and bolsters system security.

Enhancements in WSL2 GPU Support

A notable feature of this update is the resolution of a case-sensitivity issue in GPU paravirtualization within WSL2. Previously, this issue could cause GPU paravirtualization support to fail, impacting developers and users relying on GPU-accelerated tasks within WSL2. By addressing this problem, the update ensures more reliable GPU support for WSL2 users. (support.microsoft.com)

Strengthening Kernel Security

The update also enhances system security by updating the Windows Kernel Vulnerable Driver Blocklist (DriverSiPolicy.p7b). This addition blocks drivers with known security vulnerabilities that have been exploited in Bring Your Own Vulnerable Driver (BYOVD) attacks, thereby reducing the risk of such attacks.
