Abstract:
The term "VGK Driver" lacks a universal definition but typically refers to a kernel-mode driver either (1) developed for virtual GPU acceleration or (2) identified as a vulnerable driver exploited in "Bring Your Own Vulnerable Driver" (BYOVD) attacks. This paper examines both interpretations. First, we propose a reference architecture for a Virtual GPU Kernel (VGK) driver enabling GPU passthrough in virtualized environments. Second, we analyze known vulnerable drivers with "VGK" naming patterns, their exploitation vectors, and defensive strategies. The paper concludes with secure coding guidelines for kernel driver development. Fix 5: Enable TPM 2

Fix 5: Enable TPM 2.0 and Secure Boot (For newer error messages)
If Riot forces TPM 2.0:
- Reboot and enter BIOS/UEFI (usually F2, Del, or F12 during boot).
- Enable:
- Intel Platform Trust Technology (PTT) or AMD fTPM.
- Secure Boot (set to Standard or Enabled).
- Save and exit.
Fix 3: Disable Conflicting Drivers (Safe Mode Method)
BSODs involving vgk.sys usually mean another driver is interfering.
- Boot into Safe Mode (Press Shift + Restart → Troubleshoot → Advanced Options → Startup Settings → Restart → Press 4).
- Open Device Manager (
devmgmt.msc).
- Temporarily disable:
- Third-party antivirus (McAfee, Norton, AVG, Bitdefender).
- VPN TAP adapters (NordLynx, OpenVPN).
- RGB control software (Corsair iCUE, Razer Synapse).
- Reboot normally. If the error disappears, update or remove the conflicting software.
3.3 Security Mitigations in Virtual GPU Drivers
- Validate all user-supplied pointers (
access_ok, copy_from_user).
- Enforce IOCTL access control (e.g., only processes with
CAP_SYS_ADMIN).
- Use IOMMU to restrict DMA attacks.
