These affect all modern Intel processors, and (in the case of Spectre) many AMD processors and ARM cores. Spectre allows an attacker to bypass software checks to read data from arbitrary locations in the current address space; Meltdown allows an attacker to read arbitrary data from the operating system kernel’s address space (which should normally be inaccessible to user programs). Both vulnerabilities exploit performance features (caching and speculative execution) common to many modern processors to leak data via a so-called s...
