El enmascaramiento de direcciones lineales (LAM) tiene una debilidad relacionada con la ejecución transitoria como se describe en el documento SLAM[1]. A menos que se habilite la separación del espacio de direcciones lineales (LASS), esta debilidad puede ser explotable. Hasta que el kernel agregue soporte para LASS[2], solo permita LAM para COMPILE_TEST, o cuando las mitigaciones de especulación se hayan deshabilitado en el momento de la compilación, de lo contrario, mantenga LAM deshabilitado. No hay procesadores en el mercado que admitan LAM todavía, por lo que actualmente nadie se ve afectado por este problema.
