      "value": "En el kernel de Linux, se resolvi\u00f3 la siguiente vulnerabilidad: nilfs2: maneja el estado inconsistente en nilfs_btnode_create_block() Syzbot inform\u00f3 que se detect\u00f3 una inconsistencia en el estado del b\u00fafer en nilfs_btnode_create_block(), lo que provoc\u00f3 un error en el kernel. No es apropiado tratar esta inconsistencia como un error; puede ocurrir si la direcci\u00f3n del bloque de argumentos (el \u00edndice del b\u00fafer del bloque reci\u00e9n creado) es un n\u00famero de bloque virtual y se ha reasignado debido a la corrupci\u00f3n del mapa de bits utilizado para administrar su estado de asignaci\u00f3n. Por lo tanto, modifique nilfs_btnode_create_block() y sus llamadores para tratarlo como un posible error del sistema de archivos, en lugar de desencadenar un error del kernel."
