Linus Torvalds Rejects AWS Patch For Intel CPU Snoop Attack

After much debate, Linus Torvalds has rejected a controversial patch to address potential leaks of secrets from a CPU's cores.

Linux kernel head Linus Torvalds has trashed a patch from Amazon Web Services (AWS) engineers that was aimed at mitigating the Snoop attack on Intel CPUs discovered by an AWS engineer earlier this year. 

The so-called 'Snoop-assisted L1 Data Sampling', or Snoop (CVE-2020-0550), attacks affecting a range of Intel Xeon and Core CPUs were disclosed in March.
