Description Stefan Behte (RETIRED) gentoo-dev Security 2009-04-06 22:32:08 UTC
CVE-2009-1242 (
  The vmx_set_msr function in arch/x86/kvm/vmx.c in the VMX
  implementation in the KVM subsystem in the Linux kernel before on the i386 platform allows guest OS users to cause a denial
  of service (OOPS) by setting the EFER_LME (aka "Long mode enable")
  bit in the Extended Feature Enable Register (EFER) model-specific
  register, which is specific to the x86_64 platform.

security team, please try to make note of this. All bugs related to the "kernel" of 'hardened' should be assigned to 'hardened-kernel' vs 'hardened' 
Thanks in advance.
