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 separation logic has not removed 64 memory BAR access rights, which may lead to the retention of access rights in the domain after the equipment is no longer distributed.
