Microsoft rolls out emergency Windows patch for CPU vulnerability

Microsoft has released a rare, out-of-band emergency patch for Windows 10 users. But the updates are rolling out because this security flaw appears to be very unsafe. If you are running Windows 10 version 1709 (Fall Creators Update), the patch you need is labeled Security Update for Windows (KB4056892).

Fixes for Windows 7 and Windows 8 machines are also available, but won't automatically be applied until next tuesday.

According to the researchers, nearly every computer released over the last 20 years could be vulnerable.

Google has given a list of affected products and their current status for patches on one of its FAQ pages - support.google.com/faqs/answer/7622138 Microsoft responds Microsoft has also confirmed the security flaw in Intel chips in a statement to The Verge.

The good news is that a fix is already available to help you get rid of this problem. Meltdown is the easier to exploit of the two, and seems to only affect Intel processors.


FireFox also announced it has released an update to patch the flaw.

Lastly, Microsoft warns that users may see that update installation stopping at 99%, as well as elevated CPU or disk utilization if a device was reset using the Reset this PC functionality after installing KB4054022. All computers packing Intel chips that were made in the last decade suffer from a serious security issue that should be patched shortly. Intel believes these exploits do not have the potential to corrupt, modify or delete data. "The majority of Azure infrastructure has already been updated to address this vulnerability". Based on the analysis to date, many types of computing devices - with many different vendors' processors and operating systems - are susceptible to these exploits. The software update is part of a number of fixes that will protect against a newly-discovered processor bug in Intel, AMD, and ARM chipsets.

"Intel is committed to product and customer security and is working closely with many other technology companies, including AMD, ARM Holdings and several operating system vendors, to develop an industry-wide approach to resolve this issue promptly and constructively". Contrary to some reports, any performance impacts are workload-dependent, and, for the average computer user, should not be significant and will be mitigated over time.

Google has also said it is pushing out a security update to Google Chrome on January 23rd.

While Microsoft is quickly addressing the issues, the fixes will also rely on firmware updates from Intel, AMD, or other vendors that are rolling out. By the end of next week, Intel expects to have issued updates for more than 90 percent of processor products introduced within the past five years.
