  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nntfs: fix mrec_lock ABBA deadlock in rename\n\nntfs_file_fsync(), ntfs_dir_fsync() and __ntfs_write_inode() lock an\ninode's mrec_lock before taking the mrec_lock of its parent directory.\n\nntfs_rename() takes old_ni-\u003emrec_lock and old_dir_ni-\u003emrec_lock\nbefore taking new_ni-\u003emrec_lock for an existing target, or\nnew_dir_ni-\u003emrec_lock for a cross-directory rename.\nThis can deadlock when ntfs_file_fsync() or __ntfs_write_inode() holds\nthe target inode, or when ntfs_dir_fsync() holds a child target\ndirectory, while rename() holds the parent directory and waits for the\ntarget.\n\nFix this by locking the existing target inode before taking any parent\ndirectory mrec_lock. For cross-directory renames where the target parent\nis a descendant of the source parent, lock the target parent before the\nsource parent so the directory order matches the child-to-parent order used\nby ntfs_file_fsync(), ntfs_dir_fsync(), and __ntfs_write_inode().",
