The Latest on Meltdown and Spectre

As we wrote about last week, mitigation efforts for the Kernel Side-Channel Attacks also known as Meltdown and Spectre continues. Linux has been rolling out patches for its distros, and Apple has issued updates for iOS, macOS High Sierra, and Safari on Sierra and El Capitan.

Microsoft has also began issuing patches in advance of Patch Tuesday. Unfortunately, there is a significant issue with some AMD devices. Microsoft halted patching to these devices and issued the following statement:

Microsoft has received reports of some AMD devices getting into an unbootable state after installation of recent Windows operating system security updates. After investigating, Microsoft determined that some AMD chipsets do not conform to the documentation previously provided to Microsoft to develop the Windows operating system mitigations to protect against the chipset vulnerabilities known as Spectre and Meltdown.

To prevent AMD customers from getting into an unbootable state, Microsoft has temporarily paused sending the following Windows operating system updates to devices that have impacted AMD processors:

January 3, 2018—KB4056897 (Security-only update)

January 9, 2018—KB4056894 (Monthly Rollup)

January 3, 2018—KB4056888 (OS Build 10586.1356)

January 3, 2018—KB4056893 (OS Build 10240.17735)

January 9, 2018—KB4056895 (Monthly Rollup)

The process of fixing these vulnerabilities remains fluid, with new information coming out daily. Because of the unique situation, we wanted to provide a rolled up account of the information we have to date.
