CVE-2012-1601

Priority
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.
Ubuntu-Description
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.
Notes
 apw> sha1 below is from the KVM tree, though it is likely to be the right one
 apw> when it hits upstream. Patch title is:
 apw> KVM: Ensure all vcpus are consistent with in-kernel irqchip settings
 apw> now arrived in linus' tree as the sha1 below
