Meltdown and Spectre Explained ↦
If some or most of what you’ve heard or read about Meltdown and Spectre has gone over your head, then you should 💯 read this technical explainer from Matt Klein (also known for being the creator of Envoy).
I have not seen a good mid-level introduction to the vulnerabilities and mitigations. In this post I’m going to attempt to correct that by providing a gentle introduction to the hardware and software background required to understand the vulnerabilities, a discussion of the vulnerabilities themselves, as well as a discussion of the current mitigations.
Matt goes on to share graphic charts of CPUs, virtual memory, and code samples to breakdown the exploit.
