CVE-2013-1943

The KVM subsystem in the Linux kernel before 3.0 does not check whether
kernel addresses are specified during allocation of memory slots for use in
a guest’s physical address space, which allows local users to gain
privileges or obtain sensitive information from kernel memory via a crafted
application, related to arch/x86/kvm/paging_tmpl.h and virt/kvm/kvm_main.c.
