Codasip Processors Not Affected by Meltdown and Spectre

Security patches for Meltdown and Spectre are slowing older systems down

12 Enero, 2018

The two critical vulnerabilities, which exist in Intel, ARM and AMD chips built in the past two decades, allow attackers to access nearly any data stored on the device, including files, passwords and photos.

Myerson also said the tech industry is continuing to work together, to help protect users' personal and sensitive data, in a way that has less impact on the performance of older devices.

Apple has released iOS 11.2.2 with a security update for Safari that serves to guard against the Spectre bug.

Microsoft Corp said yesterday its software patches slowed down some PCs and servers, with systems running on older Intel processors seeing a noticeable decrease in performance. "To prevent AMD customers from getting into an unbootable state, Microsoft will temporarily pause sending the following Windows operating system updates to devices with impacted AMD processors at this time".

Windows Executive Vice President Terry Myerson explains that PCs running Windows 10 on Skylake or Kaby Lake processors will see performance slowdown in single digits while noticeable slowdowns will be seen on PCs running older operating systems and corporate-level server computers are going to be the most affected. "We are working quickly with these customers to understand, diagnose, and address this reboot issue". For example, the researchers explained that Meltdown can be used to circumvent containers when guests are on a shared kernel.

"We believe the performance impact of these Meltdown and Spectre fixes is highly workload-dependent", he said.

Their statement went on to explain on how they and other technology companies were fully aware of the bugs.

Microsoft has abruptly suspended Meltdown and Spectre patches for some AMD machines after complaints from users poured in to report that the update caused their machines to crash and prompted the so-called "blue screen of death". "We expect the remaining editions to be patched soon". However, AMD has neither confirmed nor denied whether these updates could impact the performance of their chips or slow down servers utilising EPYC processors. AMD has followed suit and the company is now issuing firmware updates for its own chips.
