QEMU（又名Quick Emulator）是法国程序员法布里斯-贝拉（Fabrice Bellard）所研发的一套模拟处理器软件。该软件具有速度快、跨平台等特点。 QEMU KVM 0.14.0和之前版本的“virtio_queue_notify()”函数中存在本地权限提升漏洞，当函数virtio_queue_notify()检查virtqueue数是否小于virtqueue的最大值时，虽然使用了符号比较，但如果运行恶意或有问题的程序，virtqueue数值也可能是负值，可造成内存访问virtqueue

Vulnerability Title
N/A
Source: CVE Program / CVE List V5
Vulnerability Description
The virtio_queue_notify in qemu-kvm 0.14.0 and earlier does not properly validate the virtqueue number, which allows guest users to cause a denial of service (guest crash) and possibly execute arbitrary code via a negative number in the Queue Notify field of the Virtio Header, which bypasses a signed comparison.
