Descriptions

The vmx_set_msr function in arch/x86/kvm/vmx.c in the VMX implementation in the KVM subsystem in the Linux kernel before 2.6.29.1 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.

La función vmx_set_msr en arch/x86/kvm/vmx.c en la implementación VMX en el subsistema KVM en el kernel de Linux anteriores a v2.6.29.1 en la plataforma i386 permite a los usuarios invitados del SO causar una denegación de servicio (OOPS) estableciendo el bit EFER_LME (también conocido como "modo largo habilitado") en la Extended Feature Enable Register (EFER) registro específico de modelo, lo que es específico para la plataforma x86_64.
