A vulnerability in Apple M-series chips could expose encryption keys and harm performance — and the flaw is ‘unpatchable’

A vulnerability etched into the design of Apple M-series chips has been uncovered by researchers which could allow attackers to extract encryption secret keys when performing cryptographic operations.

Six academic researchers at institutions across the US authored a paper outlining a vulnerability they dubbed ‘GoFetch’, which leaks cryptographic data from the CPU cache that hackers can use to piece together a cryptographic key.
