Intel's Cascade Lake CPUs impacted by new Zombieload v2 attack

The Zombieload vulnerability disclosed earlier this year in May has a second variant that also works against more recent Intel processors, not just older ones, including Cascade Lake, Intel's latest line of high-end CPUs -- initially thought to have been unaffected.

The attacks rely on taking advantage of the speculative execution process, which is an optimization technique that Intel added to its CPUs to improve data processing speeds and performance.
Vulnerabilities like Meltdown, Spectre, and Foreshadow, showed that the speculative execution process was riddled with security holes.

Nicknamed Zombiload v2 (CVE-2019-11135), this is a variation of the Zombieload v1 vulnerability, but one that worked on Intel's newer line of CPUs, those which the company claimed had protections against speculative execution attacks baked in at the hardware level.
