CVE-2024-53690

In the Linux kernel, the following vulnerability has been resolved: nilfs2: prevent use of deleted inode syzbot reported a WARNING in nilfs_rmdir. [1] Because the inode bitmap is corrupted, an inode with an inode number that should exist as a ".nilfs" file was reassigned by nilfs_mkdir for "file0", causing an inode duplication during execution. And this causes an underflow of i_nlink in rmdir operations. The inode is used twice by the same task to unmount and remove directories ".nilfs" and "file0", it trigger warning in nilfs_rmdir. Avoid to this issue, check i_nlink in nilfs_iget(), if it is 0, it means that this inode has been deleted, and iput is executed to reclaim it. [1] WARNING: CPU: 1 PID: 5824 at fs/inode.c:407 drop_nlink+0xc4/0x110 fs/inode.c:407 ...

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: nilfs2: evitar el uso de inodo eliminado syzbot informó una ADVERTENCIA en nilfs_rmdir. [1] Debido a que el mapa de bits del inodo está dañado, un inodo con un número de inodo que debería existir como un archivo ".nilfs" fue reasignado por nilfs_mkdir para "file0", lo que provocó una duplicación de inodo durante la ejecución. 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. [1] ADVERTENCIA: CPU: 1 PID: 5824 en fs/inode.c:407 drop_nlink+0xc4/0x110 fs/inode.c:407 ...
