Microsoft has released a new batch of Intel microcode updates for Windows 10 20H2, 2004, 1909, and older versions to fix new hardware vulnerabilities discovered in Intel CPUs.

When Intel finds bugs in their CPUs, they release microcode updates that allow operating systems to patch the behavior of the CPU to fix, or at least mitigate, the bug.

Today, an international group of researchers from Graz University of Technology, CISPA Helmholtz Center for Information Security, and the University of Birmingham disclosed new Intel CPU side-channel vulnerabilities called Platypus.

Not affecting my Ice-Lake CPU though

Older Intel CPUs are vulnerable to other security problems since years.
You can e.g. check that with Sidechannel tool from Microsoft.

Even my old Q9550 wasn't secure. This CPU was affected because of hyper threading and old CPUs aren't patched so..
