In the Linux kernel, the following vulnerability has been resolved:

fs/ntfs3: Fix memory leak if ntfs_read_mft failed

Label ATTR_ROOT in ntfs_read_mft() sets is_root = true and
ni->ni_flags |= NI_FLAG_DIR, then next attr will goto label ATTR_ALLOC
and alloc ni->dir.alloc_run. However two states are not always
consistent and can make memory leak.

1) attr_name in ATTR_ROOT does not fit the condition it will set
is_root = true but NI_FLAG_DIR is not set.
2) next attr_name in ATTR_ALLOC fits the condition and alloc
ni->dir.alloc_run
3) in cleanup function ni_clear(), when NI_FLAG_DIR is set, it frees
ni->dir.alloc_run, otherwise it frees ni->file.run
4) because NI_FLAG_DIR is not set in this case, ni->dir.alloc_run is
leaked as kmemleak reported:

Fix this by always setting is_root and NI_FLAG_DIR together.
