A principios de este mes se dio a conocer el descubrimiento de una nueva vulnerabilidad cr\u00edtica en los procesadores Intel, conocida como \u00abSpoiler\u00bb. Los especialistas que identificaron el problema informaron que los procesadores AMD y ARM no son vulnerables a \u00e9l. Ahora, la empresa AMD ha confirmado que, gracias a las caracter\u00edsticas arquitect\u00f3nicas, Spoiler no representa una amenaza para sus procesadores.<\/p>\n

\"AMD<\/p>\n

Al igual que en el caso de las vulnerabilidades Spectre y Meltdown, el nuevo problema radica en la implementaci\u00f3n de los mecanismos de ejecuci\u00f3n especulativa en los procesadores Intel. En los chips AMD, este mecanismo se implementa de manera diferente, utilizando un enfoque distinto para gestionar las operaciones en la memoria RAM y en la cach\u00e9. M\u00e1s espec\u00edficamente, Spoiler puede acceder a informaci\u00f3n parcial sobre la direcci\u00f3n (por encima de los 11 bits de direcci\u00f3n) durante las operaciones de carga. Y los procesadores AMD no utilizan coincidencias de direcciones parciales por encima de los 11 bits de direcci\u00f3n al resolver conflictos de carga.<\/p>\n

\"AMD<\/p>\n

Es importante se\u00f1alar que, aunque Spoiler, al igual que Spectre, se basa en el mecanismo de ejecuci\u00f3n especulativa, no se puede cerrar la nueva vulnerabilidad con los \u2018parches\u2019 existentes para anteriores exploits. Es decir, los procesadores Intel actuales necesitar\u00e1n nuevos parches, que pueden volver a afectar el rendimiento de los chips. Adem\u00e1s, Intel, por supuesto, necesitar\u00e1 correcciones a nivel arquitect\u00f3nico. La empresa AMD, en cambio, no tendr\u00e1 que realizar tales acciones.<\/p>\n

\"AMD<\/p>\n

Al final, se\u00f1alemos que Spoiler afecta a todos los procesadores Intel, desde los chips Core de primera generaci\u00f3n hasta los actuales Coffee Lake Refresh, as\u00ed como a los a\u00fan no lanzados Cascade Lake e Ice Lake. A pesar de que Intel fue informada del problema a principios de diciembre del a\u00f1o pasado y que ya han pasado m\u00e1s de diez d\u00edas desde que se hizo p\u00fablica la noticia sobre Spoiler, la compa\u00f1\u00eda Intel no ha presentado posibles soluciones al problema ni ha emitido una declaraci\u00f3n oficial al respecto.<\/p>\n
