Spectre is a type of side-channel attack that targets the speculative execution feature of modern CPUs. Speculative execution is a technique used by CPUs to improve performance by predicting the outcome of a branch instruction and executing the instructions ahead of time. If the prediction is incorrect, the CPU rolls back the changes and resumes execution from the correct branch.
