CVE-2017-7262

Estado: ModificadaMedia (5.5)—

El procesador AMD Ryzen con microcódigo AGESA hasta 2017-01-27 permite a los usuarios locales provocar una denegación de servicio (cuelgue del sistema) a través de una aplicación que realiza una larga serie de instrucciones FMA3, como lo demuestra el banco de pruebas Flops.
