KERNEL_SECURITY_CHECK_FAILURE stopcode BSOD when my travel laptop with Arch Linux tries to connect to my hotspot (Windows 11)

Question

I've managed to get my hotspot from my Ethernet cable connection up and running, and my phone connects to it just fine. I need that hotspot because my dormitory wifi is really weak in my room and thus isn't stable. However, when I try to connect my Arch Linux laptop to my hotspot on Windows 11, it instantly causes BSOD with stopcode "KERNEL_SECURITY_CHECK_FAILURE".

BSODs back in Windows XP days used to be much more informative, and if you were quick enough (or the PC was slow enough) for you to snap a picture of the screen with your camera, you'd be able to analyze exactly in which part of the memory the error happened, which triggered the bugcheck. That's no longer possible, where you have to use a vague stopcode and a MEMORY.DMP file that contains the dump of the memory produced by the bugcheck procedure.

My MEMORY.DMP file is 2.5 GB big, and I suppose it's not even complete (that may be because I've got 16 GB RAM). I'm not sure if bugcheck only dumps the portion of the memory where an error occured, but 2.5 GB seems a little bit too small for a memory dump to something that supposedly was in the kernel. What I can however suspect is that Wi-Fi drivers might be at fault, or perhaps Windows modules for managing Wi-Fi hotspot.

Anyway, I'm sending you the MEMORY.DMP file, hopefully it shall contain everything necessary to debug it.

MEMORY.DMP - I had to upload it to my school Sharepoint OneDrive, because my personal is too full to take that large file into account.

Solving this crash and having it fixed would be really nice, because I live in a dormitory, and this hotspot is visible in the vicinity, and I've had another student to snoop around and crack my hotspot password, and having this bug is a critical vulnerability for a DoS (Denial of Service) attack, where an attacker can use a Linux distribution that causes the BSOD to essentially crash my laptop randomly when it's in use.

Additional info that might be useful:

Windows 11 build: 27823.1000 (Insider Preview, Dev Canary channel)

RAM: 16GB DDR4

This is the picture of the BSOD (in my case, the screen is green, because I'm using an Insider Preview - GSOD).

The percentage didn't move at all, it stayed at 0% the whole time, it was like 5 minutes. I'm not waiting hours for it to move, I need to use the PC.

Answer 1

You could try the drivers from here if you haven't already.

Intel® Wireless-AC 9560

Answer 2

Hi Marek Poláček,

How is your laptop set up?

Dual boot or VirualBox etc

Why use W11 Insider on a computer for college?

Answer 3

I've got two laptops. One is used for gaming, Windows 11 (Insider Preview), with no other OS (though I do use VMware on it to launch other OSes - Windows 98, MS-DOS 6.22, and various Linux distributions, including Kali Linux). So no dualboot. The other laptop is used for travels mostly, which has Arch Linux installed (a lightweight Linux distribution with KDE Plasma, specifically chosen because the laptop only has 4 GB RAM, additional 6 GB are made using a combination of a swap partition /2 GB/ and swap file /4 GB/, making up total of 10 GB RAM).

As for why I use Insider Preview as my main system - let's say the initial impulse was simply for development purposes, since I needed that improved WSL that at the time was only available in Insider Preview. It stuck. You can call me crazy. Maybe I am. But I love it! :D

Answer 4

Can you explain how you are setting your system up, I not sure how you are trying to set up your network.

is the Linux laptop connecting directly to your phones hot spot?

Answer 5

No, it's not a phone hotspot, it's a hotspot from my gaming laptop. This is my setup: I've got 3 devices. An Android phone, and two laptops: gaming laptop with Windows 11, and travel laptop with Arch Linux.

My gaming laptop is connected to the Internet via an Ethernet cable, through my university network. This is the origin of my Wi-Fi hotspot. My gaming laptop broadcasts that hotspot. My phone and my travel laptops are clients that want to connect to it. While my phone connects to the hotspot just fine, my travel laptop crashes my gaming laptop instantly when connecting. The stop code is KERNEL_SECURITY_CHECK_FAILURE. That implies there is a driver issue that affects the Windows kernel security.
