NVD Description

Note: Versions mentioned in the description apply only to the upstream perf package and not the perf package as distributed by Centos. See How to fix? for Centos:6 relevant fixed versions and status.

The KVM implementation in the Linux kernel before 3.3.6 allows host OS users to cause a denial of service (NULL pointer dereference and host OS crash) by making a KVM_CREATE_IRQCHIP ioctl call after a virtual CPU already exists.
