It is thought that only VIA C3 CPUs are affected by this issue. The C-series processors are marketed towards industrial automation, point-of-sale, ATM, and healthcare hardware, as well as a variety of consumer desktop and laptop computers.

While industrial hardware certainly tends to get used far longer than the typical PCs, this CPU is positively ancient (a quarter century old) and chances are even industrial hardware using it has been replaced by now, or is already slated to be soon. The repository this post points to is eight years old as it is.
