Kernel crash via corrupted NTFS inode rollback
Published Nov 9, 2024 · Updated May 11, 2026
Denial of service in the Linux ntfs3 filesystem allows local users to crash the kernel by creating an inode on a corrupted mounted NTFS volume. The rollback path in ntfs_create_inode() incorrectly deletes a non-resident attribute, leaving run_is_mapped_full() to access invalid mapping state. Exploitation requires local access and a corrupted NTFS filesystem mounted with ntfs3; the demonstrated consequence is a kernel fault and service interruption.
