  "description": "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-\u003Eni_flags |= NI_FLAG_DIR, then next attr will goto label ATTR_ALLOC and alloc ni-\u003Edir.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-\u003Edir.alloc_run  3) in cleanup function ni_clear(), when NI_FLAG_DIR is set, it frees  ni-\u003Edir.alloc_run, otherwise it frees ni-\u003Efile.run  4) because NI_FLAG_DIR is not set in this case, ni-\u003Edir.alloc_run is  leaked as kmemleak reported:  unreferenced object 0xffff888003bc5480 (size 64):   backtrace:     [\u003C000000003d42e6b0\u003E] __kmalloc_node\u002B0x4e/0x1c0     [\u003C00000000d8e19b8a\u003E] kvmalloc_node\u002B0x39/0x1f0     [\u003C00000000fc3eb5b8\u003E] run_add_entry\u002B0x18a/0xa40 [ntfs3]     [\u003C0000000011c9f978\u003E] run_unpack\u002B0x75d/0x8e0 [ntfs3]     [\u003C00000000e7cf1819\u003E] run_unpack_ex\u002B0xbc/0x500 [ntfs3]     [\u003C00000000bbf0a43d\u003E] ntfs_iget5\u002B0xb25/0x2dd0 [ntfs3]     [\u003C00000000a6e50693\u003E] ntfs_fill_super\u002B0x218d/0x3580 [ntfs3]     [\u003C00000000b9170608\u003E] get_tree_bdev\u002B0x3fb/0x710     [\u003C000000004833798a\u003E] vfs_get_tree\u002B0x8e/0x280     [\u003C000000006e20b8e6\u003E] path_mount\u002B0xf3c/0x1930     [\u003C000000007bf15a5f\u003E] do_mount\u002B0xf3/0x110     ...
