Yes but these are well known hardware security flaws that are actively looked for by bad actors.Thermal issues shouldn't be a problem with the LC series i hope.
Security issues are everywhere especially with the company's that hold your data i bet they don't use AMD based machines either solely based upon security flaws and also they don't give you a choice how its held either.
This is one of reasons Intel separating further its Business Pro CPU’s from consumer CPU’s.
The newer pro version are likely to come with inbuilt Ransomware security to protect against some of the architecture flaws (they are several).
Yes fully agree everyone faces security issues in the modern internet age.
however, you can reduce risks by not using known weak links.
Someone using Intel, FireFox, 3rd Party Drive utilities to find drivers, poor online security - not using MFA, using same email for everything, not having long pass phrases.
people can learn to think secure however if they use insecure applications and hardware, they are still more open to threats.
