7 New Meltdown and Spectre-type CPU Flaws Affect Intel, AMD, ARM CPUs

Disclosed earlier this year, potentially dangerous Meltdown and Spectre vulnerabilities that affected a large family of modern processors proven that speculative execution attacks can be exploited in a trivial way to access highly sensitive information. Since then, several more variants of speculative Read More …

Microsoft, Google: We’ve found a fourth variant of Meltdown-Spectre CPU holes

A fourth variant of the data-leaking Meltdown-Spectre security flaws in modern processors has been found by Microsoft and Google researchers. These speculative-execution design blunders can be potentially exploited by malicious software running on a vulnerable device or computer, or a miscreant logged Read More …
