CPU vulnerability detection device and method based on virtual machine

The invention discloses a CPU vulnerability detection device and method based on a virtual machine. The CPU vulnerability detection device comprises a process monitoring module and a driving module. The process monitoring module is suitable for sending process information of an unknown process to the cloud server when monitoring the unknown process, and providing the process information of the unknown process to the driving module when determining that the unknown process is a process of a preset level according to a query result returned by the cloud server; the drive module is suitable forsending the process information of the unknown process provided by the process monitoring module to a preset host device, is used for monitoring whether an unknown process executes an instruction related to the CPU vulnerability or not by the host device and providing a monitoring result returned by the host device to the process monitoring module, so that the process monitoring module processes according to the monitoring
