CVE-2026-98138Hinoki check available

Unrepaired NTFS corruption via premature dirty-bit clearing

Published Sep 25, 2026 · Updated Sep 25, 2026

Incorrect volume-state handling in the Linux kernel 7.1 allows local users to suppress NTFS recovery through a filesystem sync. The ntfs_sync_fs function clears VOLUME_IS_DIRTY even when NVolErrors records a prior volume error, so later recovery treats the filesystem as clean. Exploitation requires a mounted read-write NTFS volume with a recorded error; a subsequent sync can leave existing filesystem damage unrepaired.
