" summary

The talk explains speculative execution vulnerabilities in modern CPUs, naming Spectre, Meltdown and Foreshadow/L1TF as examples, and describes how these microarchitectural flaws allow devastating attacks on protected data. It focuses on the critical nature of these bugs, uses Foreshadow/L1TF as a concrete case study, and warns that more such vulnerabilities are likely to be found due to processor complexity.
