Speculative execution improves speed by operating on multiple instructions at once-possibly in a different order than when they entered the CPU. This, however, requires access to protected kernel memory, which hackers can exploit through malicious programs.
AMD said the second Spectre variant "applies to AMD" processors and that it would issue patches for its Ryzen and EPYC processors starting this week and older chips in the coming weeks. The company determined that the problem was limited only to the oldest AMD Athlon X2-era systems capable of running Windows 10.
In addition to releasing its benchmark results for PCs, Intel said it plans to share initial data on its assessment of server platforms these next few days.
"As of now, we have not received any information that these exploits have been used to obtain customer data. However, the security of our products and our customers' data is our number one priority".
Finally, the Intel CEO highlighted "ongoing security assurance" as the third and final part of the pledge.
Intel chief Brian Krzanich said on Monday the impact of a recently discovered vulnerability in computer chips has been limited due to "remarkable" collaboration by the tech industry. "The degree of collaboration across the industry has been remarkable".
The patch Nvidia released is for the drivers that let its GPUs work with operating systems like Windows, reports Reuters, adding that while they aren't flawed, it's updating them because they interact closely with vulnerable CPUs. Security updates for affected computers will resume after it's fixed. So as long as you have the latest patches installed, you shouldn't have to worry too much about the vulnerabilities. This puts many at risk from potential attackers.
The updated and patched drivers for GeForce graphics cards, as well as Quadro and NVS GPUs, running on Windows and Linux are available now - you want to install version 390.65 for Windows - with Tesla and Grid driver updates to follow before January is out.
