What Intel’s new security flaw means for you

Intel Corp and a group of security researchers on Tuesday said they had found a new set of security flaws in its processors that will be difficult to fix and are related to problems found last year.
Intel calls the newly discovered flaws “Microarchitectural Data Sampling,” or MDS for short. The vulnerability could let hackers read nearly all data flowing through one of Intel’s chips, though the company said the attack is difficult to carry out and that it has not seen it used outside of labs.
Intel chips released this year contain a fix for the bug. But previous generations of chips will need to be patched, and in some instances that fix could slow the performance of the chip by as much as 19%, Intel said in a post announcing the news.
