Intel has revealed a vulnerability in its chips that could lead them to leak data to attackers, underlining the risks from a new flaw in modern chip designs that first surfaced last year.

Known as ZombieLoad, the problem exists in all Intel chips made since 2011, though the chipmaker said its latest microprocessors had been fixed at the hardware level to prevent the problem. Older chips will need an update to their microcode, along with updates to the operating systems running on them.
