Fix for Intel Chip Flaw Comes with a Cost: Much Slower Performance

Apple Stock Brushes Off Spectre, Meltdown Risks

Apple confirms iPhone, Mac affected by Meltdown-Spectre vulnerabilities

It said that the impacts are "workload dependent" and "average users" should only see limited or negligible impacts on performance.

Intel added that users should check with their operating system vendor or system manufacturer and apply any updates as soon as they are available.

A highly-regarded and United States government-linked cybersecurity organisation has quietly withdrawn its recommendation that users and manufacturers replace the chips in their devices to fully protect against a security vulnerability that just became public.

Microsoft has also acknowledged the issue and told CNBC (via email), "We are in the process of deploying mitigations to cloud services and have also released security updates to protect Windows customers against vulnerabilities affecting supported hardware chips from Intel, Arm, and AMD".

On Wednesday, Google and Intel disclosed "Meltdown" and "Spectre," two ways to exploit Intel, AMD, and ARM processors and get access to confidential data.

Because of the industry-wide vulnerability, it is more than computers, servers and cloud OS that are vulnerable. The said flaw could leave users' PCs exposed to cyber attacks, which will let hackers have access to sensitive or personal data inside the computer.

Desktops, laptops, cloud servers, and smartphones are affected by one or both vulnerabilities, the researchers warn.

Microsoft said that it has been working with manufacturers to counter vulnerabilities and protect customers. It will require the redesign of chip architecture and operating system software, which could have an effect on performance and efficiency. In a post on its website, Apple said updates to its operating systems for iPhones (iOS 11.2), Macs (macOS 10.13.2), and Apple TVs (tvOS 11.2) would defend against Meltdown. Rather, because key members of Google's Project Zero and data company Rambus told The New York Times that, at least in Spectre's case, this flaw is at such a level that it can not be fixed by any old security patch.

Intel said in a statement it has already issued updates "for the majority of processor products introduced within the past five years". We'll update the article once more information is available.

Intel stated that its chips are working as specified, which suggests that the "flaw" can be more accurately described as an "exploit" that attackers could take advantage of.

Two hardware bugs can be exploited to allow the memory content of a computer to be leaked. Google along with firms like Apple, AMD and Mozilla also have the same flaws in their chips, which allow products using them to be easily compromised by hackers.

Meltdown and Spectre security vulnerabilities - What are the bugs? Google says Android devices are protected if they have the latest security updates.
