Google: We fixed Spectre and Meltdown with no performance loss

Intel warns that its Meltdown and Spectre patches might introduce reliability issues on PCs and servers An Update on AMD Processor Security | AMD
Velma Reese | 13 Января, 2018, 06:06

In the meantime, Microsoft this week said it has "temporarily paused" patches for Windows customers running AMD processors after some users reported seeing the "blue screen of death" after the update was applied.

It's been a long week since we first learned about the now infamous Spectre and Meltdown chip vulnerabilities.

Intel is still diagnosing the reboot issue, but it plans to release a revised firmware update, if needed. But for now, the fix is only optional.

"Based on our most recent PC benchmarking, we continue to expect that the performance impact should not be significant for average computer users", Intel said in a statement. Others, including Epic Games, have posted screen shots, illustrating the computing drain on their systems.

Sadly, not all Chromebooks will get the software updates that would protect them from potential attacks carried out by taking advantage of the Spectre and Meltdown vulnerabilities.

While admitting that "Spectre" and "Meltdown" were two of the most complex flaws to fix in the past decade, Google has revealed the details of how it protected Gmail and other cloud services in a research shared with other tech companies, hoping they will deploy similar solutions to improve the cloud experience across the industry (via Engadget).

"Things may change, however, if you're doing something more intensive with your computer - like performing a large number of complex calculations, or processing large amounts of data".

With its head start on this issue - a luxury not every vendor had, by the way - the company was able to come up with solutions for Variants 1 and 3 as far back as September. AMD will work with Microsoft to determine the appropriate timing for distributing Windows updates. However, nearly immediately, customers began experiencing issues with their systems rebooting unexpectedly. In the wrong hands, the Meltdown and Spectre bugs can be used to steal data from any protected application on a machine, including password managers and browsers. The company pulled together hundreds of engineers in search of a better solution - a "Moonshot" as Google likes to say. Those updates can be found on Intel's site. That report cited an internal Intel document disclosing that the company identified three issues in microcode updates released over the past week meant to address the vulnerabilities.
