Windows 10: Intel Optane memory module update

Brink · Jul 11, 2018

Intel ID: INTEL-SA-00114 Product family: Intel® Optane™ Impact of vulnerability: Information Disclosure Severity rating: Moderate Original release: 07/10/2018 Last revised: 07/10/2018
Summary:
Information disclosure vulnerability in storage media in systems with Intel® Optane™ memory module with Whole Disk Encryption may allow an attacker to recover data via physical access.

Description:
Intel identified an issue where some systems configured with Whole Disk Encryption and an Intel® Optane™ memory module, may be at risk of data remaining unencrypted and potentially accessible under specific conditions.

Microsoft* BitLocker is required as the software-based Whole Disk Encryption solution on Intel® Optane™ memory enabled volumes.

Other software-based Whole Disk Encryption solutions are not supported.

Microsoft* BitLocker should be enabled before configuring the Intel® Optane™ memory module. Data migration to the Intel® Optane™ memory module takes place using the Intel® Rapid Storage Technology (Intel® RST) software.

Due to how Intel® RST software migrates data during the Intel® Optane™ memory enabling process, there is a small region on the non-Intel® Optane™ memory module that will be kept hidden from the host operating system. If Microsoft* BitLocker enablement occurs after configuring the Intel® Optane™ memory media device, this small region will not benefit from the Whole Disk Encryption and as a result, end-user data in the small region could possibly be at risk.

Affected products:
The issue potentially affects systems with Intel® Optane™ memory module and Microsoft* BitLocker enabled, based on:
• 7th Gen Intel® Core™ Desktop Processors
• 8th Gen Intel® Core™ Desktop Processors
• 8th Gen Intel® Core™ Mobile Processors
• Intel® Core™ X-Series Processors
• Intel® Xeon® E Processors
Affected configurations:
Intel® Optane™ Memory + Whole Disk Encryption

CVE ID CVE Title CVSSv3 severity CVSSv3 Vectors CVE-2018-3619 Information disclosure vulnerability in storage media in systems with Intel® Optane™ memory module with Whole Disk Encryption may allow an attacker to recover data via physical access 5.3 (Moderate) CVSS:3.0/AV/AC:L/PR:N/UI:N/S:C/C:H/I:N/A:N
Recommendations:
1. Intel requires users who want Whole Disk Encryption with Intel® Optane™ memory to use Microsoft* BitLocker. The use of other software Whole Disk Encryption solutions is not supported.
2. Enable Microsoft* BitLocker before configuring the Intel® Optane™ memory device.
3. Intel requires following these steps to ensure the Intel® Optane™ memory with Microsoft* BitLocker is configured properly:

Confirm Microsoft* BitLocker is ON. Check the Microsoft website for instructions: https://social.technet.microsoft.com...s-enabled.aspx

Follow these steps to ensure your system is properly configured:

1. Launch Intel® RST User Interface(UI)/Intel® Optane™ Memory UI
2. Disable Intel® Optane™ memory
3. Enable Intel® Optane™ memory again
§ Check the following link for detailed instructions to disable and enable Intel® Optane™ memory: https://www.intel.com/content/dam/su...stallation.pdf
§ Refer to section 2.1.4 for disabling Intel® Optane™ and section 2.1.3 for enabling Intel® Optane™ using Intel® Optane™ Memory UI
§ Refer to section 2.2.2 for disabling Intel® Optane™ and section 2.2.1 for enabling Intel® Optane™ using Intel® Optane™ Memory UI

Acknowledgements:
CVE-2018-3619 was discovered by Intel.

Intel Optane Memory

I'm waiting for an Intel Optane Memory Module to arrive.

In the meantime I'm following up

3 Installation Media Preperation (Recommended Optional Step) in

https://www.intel.com/content/dam/su...stallation.pdf

https://www.intel.com/content/dam/su...stallation.pdf

I get as far as Mount the Windows* Recovery Image:

dism/mountimage/imagefile:c:\Win10USB\windows\windows\system32\recovery\w inre.wim /Index:1 /mountdir:winre

and get

mountimage/imagefile is unknown.

Any ideas to get this working.

Intel Optane Memory

Hi,

Just read the preparation steps Intel recommends for installing the Optane module.
They sure make it very complicated. Especially considering all compatible machines are bound to support UEFI and GPT natively.
Therefore I'd recommend skipping the creation of that recovery stuff and simply mount your Win 10 ISO and copy its contents to an empty USB stick.
Then copy the Optane drivers to it in a dedicated folder.

Of course, before you begin always take an image of your system using MR Free or similar.

BTW: The correct command sysntax is shown in Intel's pdf's command prompt's screenshot. Should you want to persue that route.

Are there any issues creating and restoring Macrium Reflect systems images on a system with Intel Optane memory? My understanding is that Intel Optane memory remembers how you use the system. I was wondering how Macrium Reflect would restore that information.
