Why are they mentioning only Windows?

Perhaps because it came from a Microsoft report. Maybe they only know of this being fixed in Windows? I would assume it'd affect all OSs but then again, I certainly do not know enough about these things to understand what's going wrong here.

Linux Patched For Transient Scheduler Attacks "TSA" Impacting AMD CPUs
Made public minutes ago is Transient Scheduler Attacks (TSA) as a new class of class of speculative side channel attacks affecting AMD processors.

That'd be my assumption as well, but journalists

Thanks. So zen 5 seems fine and patch for 3 and 4 will come with a newer kernel.

I remember the days when bugs in x86 CPUs were almost unheard of. The Pentium FDIV bug and the F00F bug were considered these unicorn things.

This isn't really the same kind of bug. Those bugs made instructions emit the wrong answer, which is obviously really bad, and they're really rare. The bugs in the article make instructions take different amounts of time depending on what else the CPU has done recently, which isn't something anyone would notice except that by asking the kernel to do something and measuring the time to execute affected instructions, an attacker that only had usermode access could learn secrets that should only be available to the kernel.
