AMD will issue optional Ryzen and Epyc microcode updates for Spectre


Intel are promising updates for 90% of their CPUs introduced in the past five years by January 15, and "ongoing security assurance", outlining their plans to fund further ongoing security research, and to share any potential side-channel attack breakthroughs the company may have.

Unlike many had predicted, Meltdown-the Intel-only vulnerability that is fixed by forcing the CPU to reload its TLB when running a kernel process-wasn't the biggest headache for Google.

The Intel exec said users shouldn't feel discouraged by these snags and continue to install updates from OS makers and OEMs.

The hardware vendor said these systems are both home computers and data center servers.

The patch for the vulnerable processors requires intervention on a feature that is directly meant to boost chip performance.

China is a powerful country but we are not a weak nation", Bipin said, Times of India reports. He said the government had told the army to conduct operation "in the manner they deem fit".

Intel have released an analysis of post-mitigation performance impact, along with a table of benchmarks testing various CPUs from their last three processor generations. And thanks to the efforts of hundreds of engineers, no one has apparently noticed because the fixes haven't slowed down or degraded popular services like Google search, Google Drive, and Gmail.

Even better news is that Google has open-sourced Reptoline so that other companies can take advantage of it in their own Spectre fixes. And worse, you may not get patches at the rate you'd expect if Intel is telling system manufacturers not to issue them right now.

Earlier this week, Microsoft said Windows PCs running Intel processors from 2015 and earlier will experience "significant slowdowns" after applying some of the patches.

Recent reports have revealed that in the wake of the panic caused by the reveal of chipset flaws called Meltdown and Spectre, Nvidia has released a software patch for their CPUs. "They are not affected by these security issues", he shared. ARM says around 5 percent of more than 120 billion chips using its designs shipped since 1991 were impacted by Spectre and significantly fewer by Meltdown.

"Operating systems and software are now having to do work that the chip previously performed at very high speed", said independent security analyst Graham Cluley.
