Intel Releases November 2022 CPU Microcode For Various Functional Issues

Intel today published their "20221108" CPU microcode collection alongside announcing various security disclosures for the quarter. Fortunately on the CPU microcode side, the changes are all focused on functional issues.

The Intel 20221108 CPU microcode collection is for Core 10th Gen CPUs up through the recently released 13th Gen "Raptor Lake" processors. Today's microcode release is the first time Raptor Lake S "Core Gen13" and Ice Lake D Xeon D-1700/2700 series processors are seeing updated microcode releases.

The microcode updates today are only for Intel's consumer/client CPUs and Ice Lake D but aside from that no other Xeon / Xeon Scalable CPU microcode updates this time.

The 10th Gen through 13th Gen microcode updates are all done in the name of fixing various functional issues. See the GitHub release page for all of the new CPU microcode binaries and other details on today's update.

Separately, Intel made a number of product security disclosures -- their first big round of disclosures since August. There are security advisories ranging from the NUC firmware to their Android app, SGX, DSA, and a wide range of other Intel software. See the Intel Security Center if concerned about any of the particular advisories.
