CVE-2024-53690

Kernel warning via deleted inode reuse

Published Jan 11, 2025 · Updated May 11, 2026

Improper inode handling in Linux nilfs2 allows local users to trigger a kernel warning through operations on a corrupted NILFS2 filesystem. nilfs_iget accepts an inode whose zero i_nlink marks it as deleted, allowing nilfs_mkdir to reassign its number and duplicate the inode. Reusing that inode while removing the .nilfs and file0 directories underflows i_nlink in nilfs_rmdir; access to the mounted filesystem is required.
