CVE-2026-72190 Detail

Description

In the Linux kernel, the following vulnerability has been resolved: ntfs: fix mrec_lock ABBA deadlock in rename ntfs_file_fsync(), ntfs_dir_fsync() and __ntfs_write_inode() lock an inode's mrec_lock before taking the mrec_lock of its parent directory. ntfs_rename() takes old_ni->mrec_lock and old_dir_ni->mrec_lock before taking new_ni->mrec_lock for an existing target, or new_dir_ni->mrec_lock for a cross-directory rename. This can deadlock when ntfs_file_fsync() or __ntfs_write_inode() holds the target inode, or when ntfs_dir_fsync() holds a child target directory, while rename() holds the parent directory and waits for the target. Fix this by locking the existing target inode before taking any parent directory mrec_lock. For cross-directory renames where the target parent is a descendant of the source parent, lock the target parent before the source parent so the directory order matches the child-to-parent order used by ntfs_file_fsync(), ntfs_dir_fsync(), and __ntfs_write_inode().
