Microsoft update disables Spectre patch

Microsoft update disables Spectre patch

In fact, Microsoft actually rolled of Windows updates aimed exclusively at the AMD processors. Created to prevent problems related to Intel's flawed patches for the Spectre vulnerability, the Microsoft fixes must be downloaded manually from the company's Windows Update catalog.

The situation has raised the question of whether the Chinese companies Intel told about Spectre and Meltdown then relayed what they learned to Chinese government officials, and whether those authorities were able to exploit the chipset flaws. It was released as part of the Windows Update catalogue, which means that users will have to download and install it manually.

To Intel's credit it is working to fix the problems its patch introduced and we should have a stable patch soon. This was the microcode released by Intel in order to address Spectre Variant 2. Further fallout could likely be in relation to reports that Intel CEO Brian Krzanich sold millions of dollars' worth of personal stock before the public was made aware of the vulnerabilities, and that Intel notified a select group of customers, including Chinese tech firms, about the bugs before informing USA officials.

Thankfully Microsoft has fixed the problem, by disabling Intel's microcode altogether.

This latest move was made after Intel publicly admitted that the microcode updates it developed for this bug caused "higher than expected reboots and other unpredictable system behaviour" that led to "data loss or corruption". While Spectre can affect all CPUs to differing degrees, Meltdown is only viable on unpatched Intel systems and can be used to expose the memory of all virtual machines on a server. The Wall Street Journal reported over the weekend that Intel told some of its customers, including some Chinese technology companies, about the Spectre and Meltdown flaws before it notified the US government about the matter.
