CVE-2025-71309

CVE-2025-71309 describes a deadlock in the Linux kernel ntfs3 code where an inode mutex (ni_lock) and per-page locks can invert order, causing a hang in ntfs_read_folio() / ni_read_folio_cmpr() during frame reads. The root cause is locking order: taking ni_lock in ntfs_read_folio() before acquiri...
