| Description: | 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. A flaw was found in the Linux kernel's KVM (Kernel Virtual Machine) virtual cpu setup. An unprivileged local user could exploit this flaw to crash the system leading to a denial of service.
