Spectre / Meltdown Counter Measures

Google Project Zero and a number of researchers have discovered and made available details on two hardware flaws that affect the security of most desktop and mobile devices. Called Meltdown and Spectre, the vulnerabilities use the CPU “speculative execution” to make virtual memory available to unintended processes, possibly leading to data being read by processes not owning it. This is a low-level hardware issue affecting many models of Intel, AMD and ARM CPUs. The issue was reported by Google to the respective processor makers in June last year.
