Exploiting a Flaw in Bitmap Handling in Windows User-Mode Printer Drivers

For reasons I don't remember (time, experience), I know what the win32kfull.sys driver is responsible for. But it kind of irritated me that someone would have to take my word for it.

So I took inspiration from your post to find a definitive source from somewhere, anywhere, or something and you're absolutely right. A simple google search lists pages and pages and pages of just non-sense and potentially dangerous sites.

Not even MSDN (seemingly) has documentation on it.

I did manage to find someone's personal site that appears to be decades of their personal technical notes and findings:

* https://renenyffenegger.ch/notes/Windows/dirs/Windows/System...

* https://renenyffenegger.ch/notes/index.html

I think there is browser extension potential in here. Would it be profitable, thats the question (and the answer is most likely no)

Here is a secret trick for finding information about windows internals. Prefix your search with "Raymond Chen"

So when I did a search for

"Raymond Chen" win32kfull.sys

Near the top of the results was

https://www.ragestorm.net/Win32k%20Smash%20the%20Ref.pdf

Which seems to provide a nice overview and talk about why there are vulnerabilities there.

Someone litteraly looped through all files in system32 and generated multiple spam sites per file
