New “GoFetch” Vulnerability in Apple M-Series Chips Leaks Secret Encryption Keys

A new security shortcoming discovered in Apple M-series chips could be exploited to extract secret keys used during cryptographic operations.
Dubbed GoFetch, the vulnerability relates to a microarchitectural side-channel attack that takes advantage of a feature known as data memory-dependent prefetcher (DMP) to target constant-time cryptographic implementations and capture sensitive data
