Intel: Meltdown And Spectre Patch Slowing Our Newer Chips As Well

19 January 2018, 02:02 | Denise Dawson

OS fragmentation means that many devices won’t be patched

Mobile devices are even more vulnerable to Meltdown and Spectre than computers

Despite being considerably less exposed than Intel to the chip security flaws revealed last week, AMD has been slapped with a class-action lawsuit - this time over claims that it artificially inflated its stock price by keeping quiet about the fact that the high-profile Spectre flaws affects its CPUs.

This malware, known as Smoke Loader, looks to be an official patch but will actually let malware loose on your computer, posing potentially a greater threat than the original Meltdown and Spectre vulnerabilities. "But we have more work to do".

"While the firmware updates are effective at mitigating exposure to the security issues, customers have reported more frequent reboots on firmware-updated systems".

"We have reproduced these issues internally and are making progress toward identifying the root cause", Shenoy wrote.

To prevent further damage, the chipmaker has updated its original Meltdown-Spectre advisory, asking OEMs and cloud providers to first test its beta silicon microcode updates before the final release.

"As part of this, we have determined that similar behaviour occurs on other products in some configurations, including Ivy Bridge-, Sandy Bridge-, Skylake-, and Kaby Lake-based platforms", Shenoy says.

BVB's Aubameyang omission leaves door open for Arsenal, Liverpool
The fact Aubameyang is 28, leaving little hope of significant resale value, left members of Arsenal's hierarchy unconvinced. Arsenal now sit in the sixth position in the Premier League table with 39 points from 23 matches so far.

Meltdown and Spectre vulnerabilities have thrown much of the technology sector into a panic, representing serious weaknesses that can be exploited by hackers to access sensitive information on users´ devices.

Apple, Cisco, Dell, Fujitsu, Google, IBM, Juniper, Microsoft and Oracle are among the many vendors that must update users' firmware and operating systems with Meltdown and Spectre protections.

The company also claimed that its AMD CPUs, mostly from the Ryzen generation are not susceptible to the security flaws.

The post confirmed that some 90% of processors that are five years old or less, now have suitable patches available. The company added the patches caused a 2 percent slowdown for usual tasks such as running website servers.

On Jan. 10, I provided initial performance data results for client systems and today I have initial results to share on the data center side.

The post highlights other mitigation options that have less of a performance impact, including Google's "Retpoline" security solution, which is said to have nearly no effect on a system's speed.
