Meltdown and Spectre

Recently two CPU microarchitecture vulnerabilities were discovered by Google’s Project Zero team and independently by other researchers: Meltdown and Spectre, which affect most modern computing devices.

Both attacks involve speculative-execution side-channels. The Meltdown vulnerability, CVE-2017-5754, can potentially allow hackers to bypass the hardware barrier between applications and kernel or host memory. The Spectre vulnerability has two variants: CVE-2017-5753 and CVE-2017-5715. These vulnerabilities break isolation between separate applications. Either of these vulnerabilities could potentially be exploited to steal sensitive data from your devices.
