HP Probook 450 G9 / DRIVER_VERIFIER_DMA_VIOLATION

[DBDrivers]

Issue: BSOD accompanied with error message "DRIVER_VERIFIER_DMA_VIOLATION". 

This has started happening as of around mid-January. Computers will start randomly having blue-screens followed by the error message "The deviced attempted to access memory that it was denied access to'.

After looking at the crash dump files + Windows update driver history, I can say with high confidence the driver causing the issue is the following:

- Realtek RTL8852BE WiFi 6 802.11ax PCIe Adapter

- PCI\VEN_10EC&DEV_B852&SUBSYS_88E3103C

- Version 6001.15.155.1 (latest)

The number of affected machines appears to be growing day by day, this has been a sizeable issue where I work as we have hundreds of that specific model in circulation. 

Solution: The current solution we have is completely uninstalling the driver and installing the previous version which would be 6001.15.148.0. We have not had any other BSOD on previously affected machines after doing so.

Although this does work for now, it is not a feasible solution for the long-term as Windows Update / HPIA will automatically update it back to the latest version at a later date.

After some digging on the issue, I've found that that some people recommend disabling the DMA Protection setting in the BIOS. However, due to the security implications of disabling such feature, it is not a viable solution for us.

I really hope HP gets on the issue as soon as possible as I am not alone: Most popular post on the issue.
