It was once claimed that FreeBSD was not affected by Meltdown and
Spectre due to its architecture. This turned out to be a reckless
misjudgment within a very short time. Even though this case is not
comparable to that situation, my point is that it is irrelevant whether
a kernel is inherently less vulnerable, or even completely immune, to
certain exploits. It may be of technical interest to some, perhaps even
to the OP, to see what the situation looks like in this specific case,
but from a security perspective, it is completely irrelevant how secure
a system is compared to one or more others. The race is over, as the
attackers have long since taken control. It doesn’t matter how a kernel
is structured. So it depends on exactly what the OP wanted to know.
Whether the OP is referring explicitly to this case and its technical
background, or whether the question is to be understood more generally.
In any case, it’s not clear to me what exactly is in the OP’s interest.
