From ${URL} :

Linux kernel built for the ARM(CONFIG_ARM) platform along with the Kernel 
based Virtual Machine support(CONFIG_KVM), is vulnerable to a NULL pointer 
dereference flaw. It occurs while performing an ioctl(KVM_GET_REG_LIST) call 
on the KVM device, without first properly initialising a vCPU.

An unprivileged user/program could use this flaw to crash the kernel resulting 
in DoS.

CVE-2013-5634 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2013-5634):
  arch/arm/kvm/arm.c in the Linux kernel before 3.10 on the ARM platform, when
  KVM is used, allows host OS users to cause a denial of service (NULL pointer
  dereference, OOPS, and host OS crash) or possibly have unspecified other
  impact by omitting vCPU initialization before a KVM_GET_REG_LIST ioctl call.

Fix in 3.10 onwards
