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.


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

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)




      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:

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:

§  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
