WebApr 6, 2024 · Just like Spectre, the feature could be exploited and it could result in a vulnerability in the new processors. Speculative execution has been a part of much bigger problems in CPU microarchitecture design, showing that each design choice has its flaws. WebSpectre is a class of side channel attacks that exploit branch prediction and speculative execution on modern CPUs to read memory, possibly bypassing access controls. Speculative execution side channel exploits do not modify memory but attempt to infer privileged data in the memory. This document covers Spectre variant 1 and Spectre …
