Meltdown and Spectre hardware bugs: What to know and do

Performance impact of the recent security updates should not be significant and will be mitigated Performance impact of the recent security updates should not be significant and will be mitigated

An apparent security flaw has been reportedly found in almost every Intel processor chip made in the last decade, forcing a redesign of Linux and Windows kernels.

Intel added that the patches should reach 90% of the Intel CPUs from the past five years by the end of the week. "Based on the analysis to date, many types of computing devices - with many different vendors' processors and operating systems - are susceptible to these exploits".

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. On Wednesday, Intel's stock plunged 3.5 percent while shares in rival AMD rose sharply.

"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.

"Recent reports that these exploits are caused by a 'bug' or a 'flaw' and are unique to Intel products are incorrect", they stated. In the meantime, Intel put out software and firmware updates to deter further threats.

Developers signing non-disclosure agreements meant there had been no word on the validity of these claims from insiders who built the faulty systems. The reason this flaw is much more complex than the usual software or hardware bugs is that it's more than just a bug that can be fixed with an update. "It was made pursuant to a pre-arranged stock sale plan (10b5-1) with an automated sale schedule". So all devices from computers to smartphones to tablets are impacted by the flaws.

Of course, this news comes after Intel has already released updates directly to its processors to combat these security holes.

The Spectre flaw was more serious and it affects chips from AMD, ARM, and Intel.

Furthermore, the company also said that it will use its own microcode updates to address all of the concerns. In this particular case, attackers would only be able to observe sensitive data rather than writing any data that could allow them to take control of a computer or make any malicious changes.

Google's cyber security researchers spotted a major flaw recently in the designing of Intel CPUs and users are not happy at all.
