Descriptions
The WRMSR processing functionality in the KVM subsystem in the Linux kernel through 3.17.2 does not properly handle the writing of a non-canonical address to a model-specific register, which allows guest OS users to cause a denial of service (host OS crash) by leveraging guest OS privileges, related to the wrmsr_interception function in arch/x86/kvm/svm.c and the handle_wrmsr function in arch/x86/kvm/vmx.c.
La funcionalidad de procesamiento WRMSR en el subsistema KVM en el kernel de Linux hasta 3.17.2 no maneja debidamente la escritura de direcciones no canónicas en un registro especifico a modelos, lo que permite a usuarios del sistema operativo invitado causar una denegación de servicio (caída del sistema operativo anfitrión) mediante el aprovechamiento de los privilegios del sistema operativo invitado, relacionado con la función wrmsr_interception en arch/x86/kvm/svm.c y la función handle_wrmsr en arch/x86/kvm/vmx.c.
It was found that KVM's Write to Model Specific Register (WRMSR) instruction emulation would write non-canonical values passed in by the guest to certain MSRs in the host's context. A privileged guest user could use this flaw to crash the host.
