CVE-2024-50245Public exploit

Local system hang via mismatched inode lock subclass

Published Nov 9, 2024 · Updated May 11, 2026

Deadlock in the Linux kernel ntfs3 driver allows local users to hang the system through a concurrent NTFS directory lookup. The ntfs_lookup function takes the generic ni_lock before dir_search_u even though nested directory paths use the ni_lock_dir subclass, creating an inconsistent lock dependency that reaches mi_read. Low-privileged local access is sufficient, and the documented consequence is an availability-only system hang.
