Windows 10: Windows 10 kernel is susceptible to USB errors!? May this become a vector of attack?

It appears, that you can crash-kill Windows 10 kernel by simply plugging in and out specific USB devices unexpectedly which is a fundamental paradigm of USB

I have an old Logitech webcam with cable damaged from bending. When you move it, the contact may disappear and appear again.
Normally this should not be a problem, and it was not in windows XP, or Windows 7.

But in Windows 10, when in active video call, this causes consequential death of all the USB input, including Bluetooth, and system halt a few minutes later.
The most interesting is that it does not happen immediately. It takes minutes after the webcam "manipulation" for USB input to disappear, then for the Video output to halt... and the disk will still keep blinking its LED for some time.
Amazingly, it does not produce BlueScreen, or error messages in the log in the end. Windows just stops responding with the screen frozen.
Windows ignores power button in this state, and you have to hard-reboot the system with Reset, or by holding the power-button for 3 seconds.

So, I guess, it is a kernel level vulnerability related to usbvideo.sys system driver responding to unexpected webcam disconnect incorrectly.
Probably. The fact that USB storage surprise removal does not produce the same effect points to usbvideo.sys.


This may produce a serious danger to corporate market, where USB storage devices are often disabled for security, but USB webcams are left enabled for conferencing.

Now imagine, if a webcam can damage the system so easily, maybe some malicious device with a webcam GUID can inject a code into kernel space the same way? Without any trace in the system!


P.S. System specs:

I tried it on two X79 based motherboards, not a new hardware, but well supported with Microsoft-bundled drivers. THe boards are quite different, from different manufacturers with different BIOSes. In both configurations the RAM was tested with overload random patterns by TestMem5 tool; it is not a memory failure.

Tried both, Intel and addon USB controllers. The problem arises in every configuration, but only with webcam. So, probably it is the .sys driver in Windows.

Windows 10 USB boot

Hi there, am not a windows 10 expert. I have a pc in the bedroom on windows 10, I messed up the bootloader trying to fix the xp on that system.

System wont boot, trying to repair via win 10 usb installer.

Downloaded the media creation tool to install windows 10 installer on usb stick. Not compatible with a host of usb sticks I have. Tried the usb sticks that others use, but I think they use rufus; as the media creation tool by win 10 does not detect the usb stick.

So quick question, the win10 machine i am trying to repair the bootloader is a win7 upgraded to win10.
If i were to use the usb win10 installer to "repair installation" does the version of the iso downloaded via the media creation tool matter?

There is three options:
Windows 10
Windows 10 Home
Windows 10 N

Also is there a step by step instead of using rufus as I want to try an alternative method of creating a usb win 10 installer. Preferably with more compatibility.

System is a asus sabertooth 990 (r2?) with AMD phenom X 6.

Also is there any other software I can load onto the usb that can repair the bootloader easily?
That would be the ideal alternative. Thanks
