      "value": "En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: pstore/ram: soluciona el fallo al establecer el n\u00famero de CPU en un n\u00famero impar. Cuando el n\u00famero de n\u00facleos de CPU se ajusta a 7 u otros n\u00fameros impares, el tama\u00f1o de la zona se convertir\u00e1 en un n\u00famero impar. La direcci\u00f3n de la zona se convertir\u00e1 en: direcci\u00f3n de zona0 = BASE direcci\u00f3n de zona1 = BASE + tama\u00f1o_zona direcci\u00f3n de zona2 = BASE + tama\u00f1o_zona*2 ... La direcci\u00f3n de zona1/3/5/7 se asignar\u00e1 a va no alineada . Eventualmente se producir\u00e1n fallas al acceder a estos va. Entonces, use ALIGN_DOWN() para asegurarse de que el tama\u00f1o de la zona sea uniforme para evitar este error."
