Critical bugs in computer chips spark panic — Intel flaw

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

Mike Ybarra, Xbox platform lead, tweeted that the security architecture of Xbox already includes mitigation against Meltdown and Spectre vulnerabilities.

Intel says it will have released patches to address major CPU security flaws for 90 percent of recently-released chips by next week.

And the Intel news continues to trickle out regarding its latest processor-gate crisis. However, a flaw allows malicious code to read system memory and thus gain access to passwords, encryption keys, and other sensitive information.

In recent days, some have speculated that the KPTI technique would cause "significant performance slowdowns", especially for cloud services.

It's worth noting Google's warning that, though it may have patches, there's still the risk of a new Meltdown or Spectre-related exploit being discovered in the future.

Computers and laptops powered by Intel and AMD processors are vulnerable, while iPhones and Android phones using ARM chips are also insecure.

For the average computer user, Intel says: "Check with your operating system vendor or system manufacturer and apply any available updates as soon as they are available".

While the revealations claimed that the security bug is affecting the devices with processors from AMD as well. "AMD processors are not subject to the types of attacks that the kernel page table isolation feature protects against", AMD software engineer Tom Lendacky wrote.

Intel, Santa Clara, Calif., declined to comment on the lawsuits.

Apply the applicable firmware update provided by your device manufacturer.

Microsoft, Apple and Google have addressed the critical security bug with the December or January Update. All three cite the security vulnerability and Intel's delay in public disclosure.

According toApplelnsider, Apple has issued a partial fix to the issue with December's macOS 10.13.2. There are vulnerabilities, but it's businesses and government organizations that are already most susceptible to hacking attempts that will want to make sure everything's on lockdown. The patches, however, will have some performance effects, noting that they will be at frustrating levels pegged at zero to 30 percent level.

A site, Meltdownattack.com, hosted by the Graz University of Technology - researchers from which also reported both Meltdown and Spectre - has further details. In cases where performance hits are higher, the company expects that future "improvement of the software updates should mitigate that impact". His fire sale of sorts was part of a 10b5-1 plan, which is a mechanism designed to help corporate insiders avoid accusation of insider trading by setting up plans to sell predetermined numbers of shares at a specific time.
