Due to the complexity and size of the Android kernel, as well as the sheer diversity of the Android ecosystem, it's difficult to fix every single exploit. Additionally, the Android kernel consists of thousands and thousands of lines of code that are out of tree. However, as we all know, these updates aren't rolled out as regularly by all OEMs as we would like them to be. This, amongst others, is done regularly by the monthly Android security updates. Improving security by fixing exploitable code is a very important aspect of kernel development. OnePlus 8 Pro XDA Forums What is Control Flow Integrity and how is it related to hardening? The mechanism is called Control Flow Integrity (CFI), which is designed to be a runtime hardening feature, but could also be classified as a bug-finding tool - making it quite distinctive. Eventually after repeating and choosing the option below UEFI it entered what looked like a Bios screen and after side scrolling I noticed a line for Intel Virtualization which was marked as 'Enabled'.**Ĭan anyone please offer advice on how I can get Memory Integrity enabled? I like to have things as secure as possible.XDA Recognized Developer Freak07, better known as the maintainer of Kirisakura kernel, has now introduced a nifty security feature to the OnePlus 8 Pro through his custom kernel. When I tried to open the UEFI (Holding F10 on a Medion Akoya E15407) I first tried entering UEFI, but after selecting English as the language I then got an error message along the lines of "No image, contact customer service". **I read somewhere that Hardware Virtualization needed to be On in the UEFI/Bios. After the required restart my laptop is still hanging on the Medion logo before Windows starts up and I am having to press and hold power to turn off and on again to restart windows, but Memory Integrity remains off** **I followed a guide that showed me how to 'Refresh/Reinstall' Windows Defender and Switch the HVEC to 'Enabled' in the Registry. Would be glad of any help getting this turned on as I like to have things properly secured where I can. It has 8GB RAM and well over 64GB of SSD space remaining. Processor: Intel(R) Core(TM) i7-1065G7 CPU 1.3GHz, 1498 Mhz, 4 Core(s), 8 Logical Processor(s) I don't understand why it keeps going off? I have not altered any settings that I can think of that would have effected this.Ĭould someone help me understand what's happening, why's it happening and how I could get Memory Integrity to stay on.įrom my System Information I have the following: When I run through the same procedure, as above, after I press 'Restart' my laptop begins the restart process but then hangs on the Medion logo before Windows 11 starts. Now maybe a week or so later it appears Memory Integrity has somehow been turned back off again. When it finished starting up Memory Integrity appeared to be on as there was no flag on Windows Security. I hit 'Restart' and my laptop automatically restarted itself. The system showed it was running a scan for incompatible drivers, didn't seem to find any and then put up a notifcation saying something like 'To enable changes a restart is required'. I noticed this flag before and went into Windows Security and flicked the tab to 'On'. I'm using a Medion Akoya Notebook and Windows Security is flagging that Memory Integrity is not turned on and my device maybe vulnerable.
