En procesos multihilo donde fdget() toma la ruta lenta, esto fuga permanentemente una referencia de archivo por llamada, fijando la estructura \u0027struct file\u0027 y los objetos del kernel asociados en memoria. Un usuario local sin privilegios puede explotar esto para causar agotamiento de la memoria del kernel.
