"value": "En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: drm/amd/display: activa DMCUB antes de enviar un comando [Por qu\u00e9] Podemos quedarnos quietos intentando enviar comandos cuando DMCUB no est\u00e1 encendido. [C\u00f3mo] Para funciones que se ejecutan dentro de un contexto de DC o bloqueo de DC, podemos ajustar las llamadas directas a dm_execute_dmub_cmd/list con c\u00f3digo que salga de las optimizaciones de energ\u00eda inactivas y se vuelva a permitir una vez que hayamos terminado con el env\u00edo del comando en caso de \u00e9xito. Para env\u00edos directos de DM, el DM deber\u00e1 gestionar la secuencia de entrada/salida manualmente. No podemos invocar un comando DMCUB directamente dentro del asistente de ejecuci\u00f3n de DM o podemos bloquearnos."
