A massive bug in cpus intel would affect up to 35% of its performance

A news story is emerging that has spread like wildfire on Reddit. Apparently a massive security flaw is happening under Intel processors (currently under embargo) that would directly affect large cloud service providers like Amazon and Google (and many others). The solution to this problem would be dramatically reducing the performance of Intel equipment by up to 35%.
A massive security flaw would affect the performance of Intel equipment
People have noticed a recent development in the Linux kernel quite important and too fast for Linux standards. The "official" reason is to incorporate a prevention technology called KASLR, which most security experts consider almost useless.
There are also some unusual and suspicious things going on: the documentation is missing and some of the comments are deleted.
The bug would be affecting a low-level core feature (virtual memory) and has severe performance penalties when applying a patch: 29% for an i7-6700 and 34% for an i7-3770S, according to grsecurity's Brad Spengler. This problem would not be present on AMD CPUs. The kernel signal is called X86_BUG_CPU_INSECURE and its description is "CPU is insecure and needs kernel table isolation" .
Microsoft appears to have been aware of this issue since November and was working on a patch since then.
Cloud-computing providers the most affected
What is being speculated at the moment is that there is a possible massive failure of Intel's CPU hardware that directly opens up serious vulnerabilities in large cloud-computing providers that offer shared hosting and other services. So this failure would not affect, at the moment, the domestic processors (The series that we usually buy mortals).

It is normal for Intel to want to keep this a secret, but it seems that everything will finally come out. For this reason we believe that if AMD quickly moves tab with its AMD EPYC it can do enough damage to Intel in these first months. What do you think about this bug?
