SAN FRANCISCO — Computer security experts have discovered two major security flaws in the microprocessors inside nearly all of the world’s computers.
The two problems, called Meltdown and Spectre, could allow hackers to steal the entire memory contents of computers, including mobile devices, personal computers and servers running in so-called cloud computer networks.
There is no easy fix for Spectre, which could require redesigning the processors, according to researchers. As for Meltdown, the software patch needed to fix the issue could slow down computers by as much as 30 percent — an ugly situation for people used to fast downloads from their favorite online services.
