amd64-microcode (AMD CPU microcode patches) is vulnerable to Memory Integrity Loss. The vulnerability is caused due to Improper or Unexpected behavior of the INVD instruction in some AMD CPUs. It can allow an attacker with a malicious hypervisor to affect cache line write-back behavior of the CPU leading to a potential loss of guest virtual machine (VM) memory integrity.
