The Spectre and Meltdown flaws revealed some cripping vulnerabilities in all sorts of chipsets, including Intel, AMD and ARM CPUs. While the entire tech industry worked (albeit late) to patch the flaws as much as they could, the fear of future attacks always remained. The Meltdown vulnerability was the easier of the two to fix, but the Spectre vulnerability remained open as it was an architectural flaw that allowed hackers to access the kernal layer and extract data. There were two variants of Spectre — Variant 1 and Variant 2 which explained how the flaw could be used to exploit the speculative execution ability of CPUs. However, there seems to be more ways to exploit the flaw, and an entirely new set of exploits are reportedly on the way.
