      "value": "En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: remoteproc: mediatek: aseg\u00farese de que el b\u00fafer IPI encaje en L2TCM. La ubicaci\u00f3n del b\u00fafer IPI se lee desde el firmware que cargamos en el procesador System Companion, y no se garantiza que tanto la SRAM ( L2TCM) que se define en el nodo del \u00e1rbol de dispositivos es lo suficientemente grande para eso, y si bien esto es especialmente cierto para SCP de m\u00faltiples n\u00facleos, tambi\u00e9n es \u00fatil verificar las variantes de un solo n\u00facleo. No realizar esta verificaci\u00f3n puede hacer que este controlador realice operaciones de lectura y escritura fuera del l\u00edmite L2TCM, lo que resultar\u00e1 (en el mejor de los casos) en un p\u00e1nico en el kernel. Para solucionarlo, verifique que el b\u00fafer IPI encaje; de lo contrario, devolver\u00e1 una falla y se negar\u00e1 a iniciar el n\u00facleo SCP relevante (o el SCP en absoluto, si es de un solo n\u00facleo)."
