Researchers who devised the original Meltdown and Spectre attacks disclosed seven new variants that leverage on a technique known as transient execution. In January, white hackers from Google Project Zero disclosed the vulnerabilities that potentially impact all major CPUs, including the ones manufactured by AMD, ARM, and Intel. The expert devised two attacks dubbed Meltdown (CVE-2017-5754) and Spectre (CVE-2017-5753 and CVE-2017-5715), which could […]
