"value": "En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: parisc: BTLB: soluciona el problema al configurar BTLB al iniciar la CPU. Al usar hotplug y activar una CPU de 32 bits, solicite al firmware la informaci\u00f3n de BTLB para configurar la est\u00e1tica ( bloque) Entradas TLB. Para eso se necesita acceso de escritura a la estructura est\u00e1tica btlb_info, pero como est\u00e1 marcada como __ro_after_init, el kernel falla por defecto y faltan permisos de escritura. Solucione el problema eliminando la anotaci\u00f3n __ro_after_init."
