Description (English)
Xen is an open-source virtual machine monitor product. The product enables different and incompatible operating systems to operate on the same computer and supports migration during operation to ensure proper operation and avoid loss of power. Xen has a security loophole, which stems from the fact that the IBPB has been bypassed in context-to-switch logic, which could lead to contamination of the branch-target buffer zone.
