La compa\u00f1\u00eda Google ha presentado la iniciativa kvmCTF, bajo la cual los investigadores de seguridad pueden recibir recompensas monetarias por identificar vulnerabilidades en el hipervisor KVM (Kernel-based Virtual Machine). El inter\u00e9s de Google en KVM se debe al uso de este hipervisor en el servicio Google Cloud, as\u00ed como en las plataformas Android y ChromeOS (CrosVM se basa en KVM). Para recibir la recompensa, debe demostrarse una explotaci\u00f3n de un entorno CTF (Capture the Flag) especialmente preparado basado en un n\u00facleo Linux reciente, que ejecuta una m\u00e1quina virtual, acceso a la cual se proporciona mediante solicitudes. Se invita al atacante a explotar una vulnerabilidad en el subsistema KVM<\/a> en el n\u00facleo de Linux, que garantiza el funcionamiento del sistema host en este entorno.<\/p>\n

Se ofrece un pago de 250 mil d\u00f3lares por descubrir una vulnerabilidad previamente desconocida que permite salir de una m\u00e1quina virtual, y 100 mil d\u00f3lares por vulnerabilidades que permiten escribir en \u00e1reas de memoria arbitrarias. Tambi\u00e9n se ofrecen 50 mil d\u00f3lares por vulnerabilidades que conducen a la lectura de \u00e1reas de memoria arbitrarias o escritura en \u00e1reas de memoria adyacentes, 20 mil d\u00f3lares por una vulnerabilidad DoS, y 10 mil d\u00f3lares por la lectura de \u00e1reas de memoria adyacentes. La recompensa por escribir o leer en un \u00e1rea de memoria arbitraria se puede obtener al modificar o obtener el valor de una direcci\u00f3n espec\u00edfica en la memoria, y en el caso de \u00e1reas adyacentes, por errores identificados por la herramienta de depuraci\u00f3n KASAN (Kernel Address Sanitizer), como desbordamientos de buffer o acceso a \u00e1reas de memoria que ya han sido liberadas. La recompensa por una vulnerabilidad DoS se paga al identificar la desreferencia de un puntero nulo (null-ptr-deref en KASAN).
