WebThe Spectre attack [ 1] has received massive coverage since the beginning of 2024, and by now, it is likely that everyone in computer science has at least heard about it. Spectre exploits the fact that speculative execution resulting from a branch misprediction may reveal private data to an attacker. WebSpectre Overview Go 1.15 adds support for enabling code generation adjustments to mitigate the effect of two variants of the Spectre family of CPU vulnerabilities. The compiler and assembler both have a new flag -spectre that is given a list of Spectre mitigations to enable, as in -spectre=index or -spectre=index,ret.
