That said, exploiting these flaws requires an attacker to obtain malicious access to a machine and possess the ability to run arbitrary code. It's not exploitable through malicious websites.

and it probably has to attack through the virtual machine environment

In a worst-case scenario, successful attacks carried out using TSA-L1 or TSA-SQ flaws could lead to information leakage from the operating system kernel to a user application, from a hypervisor to a guest virtual machine, or between two user applications.

so it is a far fetched exploit needing specific conditions that are generally not available for 99% of the machines outside the lab where this is happening.

its FUD

It's pretty relevant to hosting providers, especially VPS providers. But if you have an AMD processor in your home PC / laptop, not really relevant to you.
