Several researchers, including a member of Google's Project Zero team, found that a design technique used in chips from Intel, Arm and others could allow hackers to access data from the memory on your device. The problem impacts processors going back more than two decades and could let hackers access passwords, encryption keys or sensitive information open in applications. 

The flaws, known by the names Spectre and Meltdown, aren't unique to one particular chipmaker or device. Instead, they impact everything from phones to PCs and servers.
