"value": "En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: nilfs2: evitar el uso de inodo eliminado syzbot inform\u00f3 una ADVERTENCIA en nilfs_rmdir. [1] Debido a que el mapa de bits del inodo est\u00e1 da\u00f1ado, un inodo con un n\u00famero de inodo que deber\u00eda existir como un archivo \".nilfs\" fue reasignado por nilfs_mkdir para \"file0\", lo que provoc\u00f3 una duplicaci\u00f3n de inodo durante la ejecuci\u00f3n. Y esto causa un desbordamiento de i_nlink en operaciones rmdir. El inodo es utilizado dos veces por la misma tarea para desmontar y eliminar los directorios \".nilfs\" y \"file0\", lo que activa una advertencia en nilfs_rmdir. Evite este problema, verifique i_nlink en nilfs_iget(), si es 0, significa que este inodo ha sido eliminado y se ejecuta iput para recuperarlo.
