Smartphone Users Beware: Chip Flaw Affects Mobile Devices

Domingo, 14 Ene, 2018

Reports had claimed that any potential patch or update for the flaws might impact performance by up to 30 per cent, but Intel has now denied this, saying that any impact would be minimal, and would mitigate itself over time.

Chips potentially affected date back more than five years, with some products listed on Intel's website about the vulnerabilities having been introduced as far back as 2008. As a result of the design flaw, AMD shares rose 5.2 % Wednesday as Intel shares dropped 3.4 %.

While Intel claims that the stock sale was part of a planned divestiture, Krzanich (below, right) put the plan in place only in October, the report said.

"In addition, many operating system vendors, public cloud service providers, device manufacturers and others have indicated that they have already updated their products and services", the company said."In addition, many operating system vendors, public cloud service providers, device manufacturers and others have indicated that they have already updated their products and services", the company said.

Meltdown is a failure of the isolation between the operating system of a computer, and the user's applications. Side channel analysis exploit gives cyber attackers the ability to observe the content of privileged memory, which exploits a speculative execution to go around different privilege levels, Intel explained. This may be applied to protect sensitive binaries (such as operating system or hypervisor implementations) from branch target injection attacks against their indirect branches.

Microsoft and Google have said they expect few performance problems for most of their cloud computing customers. Android devices with the latest security update, published earlier this month, are protected, while online services like Google Apps, G Suite, and the Google App Engine require no user action.

Will the patch for Meltdown and Spectre slowdown my device?

The vulnerability which affects processors from Intel, AMD, and ARM could allow hackers to steal passwords and other secret data.

It's been a rocky start to 2018 for the computer security industry.

A site, Meltdownattack.com, hosted by the Graz University of Technology - researchers from which also reported both Meltdown and Spectre - has further details. They've all been filed on behalf of consumers on the basis of lost performance, but we don't have any information yet showing that consumer applications are impacted by Meltdown or Spectre.
