Spoiler, the cpus intel core affected by a new vulnerability

In early 2018, the world of processors was shaken by the Specter and Meltdown vulnerabilities, which mainly affected Intel. Now a major new vulnerability is emerging , this is SPOILER.

SPOILER is the latest speculative attack to be discovered on Intel processors

Specter and Meltdown were the first of a new class of processor vulnerability, leveraging speculative execution to allow hackers to access previously inaccessible data. Fortunately, these vulnerabilities are extremely difficult to exploit and have not been used by any known malware, at least as far as we know.

SPOILER is the latest speculative attack to be discovered. The name "SPOILER" comes from the speculative (Sp) nature of the holding and how the problem spoils existing security measures. At this time SPOILER is known to only affect Intel processors, specifically the Core series.

Affects Core, AMD and ARM chips do not have this problem

Both AMD and ARM processors were investigated as well, which can be read here, although neither of them exhibited the same behaviors as the Intel chips. The problem was found to affect Intel processors regardless of the operating system used and to work in both virtual machines and sandboxing environments.

As reported, Intel was informed about SPOILER on December 1, 2018, and so far the company doesn't appear to have any patches to fix the problem.

Speaking to The Register , Ahmad Moghimi, one of the authors of the article SPOILER, stated that “My personal opinion is that when it comes to the memory subsystem, it is very difficult to make changes and it is not something that can be easily patched with a microcode without losing tremendous performance , " adding " I don't think we'll see a patch for this type of attack in the next five years and that could be one reason why they haven't released a CVE.
