The Spectre class of vulnerabilities was given that name because, it was
thought, these problems would haunt us for a long time. As the fourth
anniversary of the disclosure of Meltdown and
Spectre approaches, there is no reason to doubt the accuracy of that
name. One of
the more recent Spectre variants goes by the name “straight-line
speculation”; it was first disclosed in June 2020, but fixes are still
trying to find their way into the compilers and the kernel.
