Windows 10: System detected an overrun of a stack-based buffer in this application

No malware detected, i did system repair from usb not long time ago and didn't do anything on my pc. Why i have already this garbage ??? It happens when i try access focus assist menu from windows setting. Gonna try sfc and dism. But i don't want repair again, it is exhausting to do that every day literally ! Is always something. Someone know better solution ?

:)

 

Help with this? 'The system detected an overrun of a stack-based...'

On a Windows 10 desktop today there was this error message...

“The system detected an overrun of a stack-based buffer in this application. This overrun could potentially allow a malicious user to gain control of this application“

Any suggestion as to what the problem is and how to rectify the problem?

i got this recently "logonui.exe the system detected an overrun of a stack-based buffer" may you explain why that error happened?

This sounds like an error generated from something written in C++

As the message refers to a specific application, it could be that by inspecting that dialogue window you could determine its origin.
E.g. using
Window Detective Alternatives and Similar Software - AlternativeTo.net
- has a target you can drag over a window to identify the process- as does
Process Explorer (from MS)

Have you installed a new program recently? Updated one? Added any new hardware?

If you search for
The system detected an overrun of a stack-based buffer in this application
as I assume you have, you will find many results - nothing that's immediately helpful quickly- but worth looking through if you spend some time. Some are simply waffle and no solution.

Beware of pages that are constructed as if to give some solution but look as if some bot has simply put together some generic text blocks, along with a recommendation to download some tool with the dreaded big green download button.

Make sure you read things from reputable sites only e.g. this technical discussion
Kernel_Security_Check_Failure | Tom's Hardware Forum
- where you will find
ERROR_CODE: (NTSTATUS) 0xc0000409 - The system detected an overrun of a stack-based buffer in this application. This overrun could potentially allow a malicious user to gain control of this application.

There it's indicating a problem in low level software- nothing necessarily malicious.

If you can identify the source, you're part way there. If it's a driver - and some programs install drivers other than those needed purely as hardware drivers- a program like Autoruns can let you disable startups in the hope of identifying the source by elimination.

To be able to do that, the message needs to be reproducible- when does it occur? Each time you log in? Each time you run a particular program? How often?
