ROG Zephyrus G16 (2024): Errors when going into Safe Mode on a complete fresh install

Level 7

Hi all,

I am  very worried about something I found out with a complete new computer, fresh install. The only thing that was installed on the new computer was Brave, without any extensions. 

Just for the sake of a test, I forced after going through the first time setup process, into Safe Mode. The reason why I wanted to go into safe mode is just to check how Safe Mode performs on this new laptop (the ROG Zephyrus G16 GU605MY)
I noticed the following issues:
1. It is impossible to log into Safe Mode unless you setup a local password due to the lack of Internet connectivity as wifi is not enabled, no matter what safe mode version you choose (with or without network)

2. And here is the more scary part: I get a very ugly message that looks like this:

CTFMON.EXE - System error: 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.

As this is a brand new PC with a fresh copy of Windows 11 with no other software installed except the Brave browers, I decided to do a memory test. It seems no errors were found. I think everybody should do this test as the memory is soldered to the main board and if there are errors, better find them out now instead of later when the warranty period has passed. 

So it seems that the original windows is either corrupt or has a malicious software to start from or has corrupt files. 

I hope Asus digs into this and if someone of you can confirm you get the same issue, we should notify Asus immediately. 

Thanks for your attention and sorry I couldn't make this post shorter.
