CVE-2009-3640 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2009-3640):
  The update_cr8_intercept function in arch/x86/kvm/x86.c in the KVM
  subsystem in the Linux kernel before 2.6.32-rc1 does not properly
  handle the absence of an Advanced Programmable Interrupt Controller
  (APIC), which allows local users to cause a denial of service (NULL
  pointer dereference and system crash) or possibly gain privileges via
  a call to the kvm_vcpu_ioctl function.
