Meltdown and Spectre

Google’s Project Zero team( researcher, Jann Horn, demonstrated that malicious actors could take advantage of speculative execution to read system memory that should have been inaccessible. For example, an unauthorized party may read sensitive information in the system’s memory such as passwords, encryption keys, or sensitive information open in applications.) discovered serious security flaws caused by “speculative execution,” a technique used by most modern processors (CPUs) to optimize performance.

These vulnerabilities affect many CPUs, including those from AMD, ARM, and Intel, as well as the devices and operating systems running on them.

Desktop, Laptop, and Cloud computers may be affected by Meltdown. Intel processor which implements out-of-order execution is potentially affected, which is effectively every processor since 1995 (except Intel Itanium and Intel Atom before 2013)
Because Meltdown and Spectre are flaws at the architecture level, it doesn’t matter whether a computer or device is running Windows, OS X, Android, or something else — all software platforms are equally vulnerable.
