Meltdown and Spectre are attacks that exploit speculative execution, the way processors predict commands. Meltdown and Spectre exploit the way speculatively executed instructions can bypass process memory protection. These vulnerabilities are particularly harmful to multi-user server environments, giving malicious users access to users’ confidential information.
