Two major flaws in computer chips could leave a huge number of computers and smartphones vulnerable to security concerns, researchers revealed Wednesday.
And a U.S. government-backed body warned that the chips themselves need to be replaced to completely fix the problems.
Called Meltdown and Spectre, the flaws exist in processors, a building block of computers that acts as the brain. Modern processors are designed to perform something called “speculative execution.” That means they predict what tasks they will be asked to execute and rapidly access multiple areas of memory at the same time.
