Apple CPUs: side-channel attack via DMPs (GoFetch)

[madires]

https://gofetch.fail/:

GoFetch is a microarchitectural side-channel attack that can extract secret keys from constant-time cryptographic implementations via data memory-dependent prefetchers (DMPs).

Affected CPUs are m1, m2 and m3.

This is actually not the first DMP vulnerability that has been found: https://www.prefetchers.info/
