I just checked the microcode release https://github.com/intel/Intel-Linux-Processor-Microcode-Data-Files/release= s. The microcode fix hasn't been released yet, but the erratum is already in SPR/EMR specification. e.g., for SPR, SPR141. VM Exit Following MOV to CR8 Instruction May Lead to Unexpected IDT Vectoring-Information Problem: Under certain conditions, a VM exit following execution of the MOV= to CR8 instruction may unexpectedly result in setting the Valid bit (bit 31) of the IDTVectoring Information Field in the Virtual Machine Control Structure (VM= CS). Implication: Depending on the operation of the virtual-machine monitor (VMM= ), this may result in unexpected VM behavior. Workaround: It may be possible for the BIOS to contain a workaround for this erratum --=20 You may reply to this email to add a comment.
