Until I see more info I’m skeptical. This could be nothing more than a timing delay when attempting to access certain kernel memory locations. The fact that there is no demonstrable exploit code makes me think it is just theoretical.

Now that it is ‘known’ there will be those who will exploit it................

It has already been demonstrated that small chunks of Ring 0 memory can be returned to user mode code.

I am skeptical as well. The Intel response is that they realize there is a vulnerability (they refuse to call it a bug): https://newsroom.intel.com/news/intel-responds-to-security-research-findings/ and they will patch around it. But if it is like the rowhammer DRAM attack in the past, using it for exploitation will be difficult and the attack will be easy to prevent.
