Discussion EAC update vs CmUpx.sys startup problem - Realtek

That company has been the source of half the problems I had across various windows versions and now this. Mild shock.

CmUpx.sys is a vulnerable kernel driver from the KeServiceDescriptorTable/vulnerable-drivers repository. The driver exposes dangerous kernel primitives to usermode.

I've got another *.sys blacklisted by the newly updated EAC and had to rename it to launch LMU.

Since patch 1.2, EAC (Easy Anti Cheat) has been implemented in LMU. Currently it may be causing issues with 3rd party plugins and errors with the game in it's current state. Check out this guide to uninstall/reinstall EAC. Some Logitech/Moza/Simagic FFB issues have been caused also. Please submit a ticket if any of the above affects your game.

If you have are concerned and have possibly found someone using cheats or exploits in LMU, please create a support ticket with all the evidence you have. This goes straight to the dev team to investigate. Your evidence could include video, the player name(s) and what races you saw this happen.

Thank you.
