      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nfs/ntfs3: Fix memory leak if ntfs_read_mft failed\n\nLabel ATTR_ROOT in ntfs_read_mft() sets is_root = true and\nni->ni_flags |= NI_FLAG_DIR, then next attr will goto label ATTR_ALLOC\nand alloc ni->dir.alloc_run. However two states are not always\nconsistent and can make memory leak.\n\n 1) attr_name in ATTR_ROOT does not fit the condition it will set\n is_root = true but NI_FLAG_DIR is not set.\n 2) next attr_name in ATTR_ALLOC fits the condition and alloc\n ni->dir.alloc_run\n 3) in cleanup function ni_clear(), when NI_FLAG_DIR is set, it frees\n ni->dir.alloc_run, otherwise it frees ni->file.run\n 4) because NI_FLAG_DIR is not set in this case, ni->dir.alloc_run is\n leaked as kmemleak reported:\n\nunreferenced object 0xffff888003bc5480 (size 64):\n  backtrace:\n    [<000000003d42e6b0>] __kmalloc_node+0x4e/0x1c0\n    [<00000000d8e19b8a>] kvmalloc_node+0x39/0x1f0\n    [<00000000fc3eb5b8>] run_add_entry+0x18a/0xa40 [ntfs3]\n    [<0000000011c9f978>] run_unpack+0x75d/0x8e0 [ntfs3]\n    [<00000000e7cf1819>] run_unpack_ex+0xbc/0x500 [ntfs3]\n    [<00000000bbf0a43d>] ntfs_iget5+0xb25/0x2dd0 [ntfs3]\n    [<00000000a6e50693>] ntfs_fill_super+0x218d/0x3580 [ntfs3]\n    [<00000000b9170608>] get_tree_bdev+0x3fb/0x710\n    [<000000004833798a>] vfs_get_tree+0x8e/0x280\n    [<000000006e20b8e6>] path_mount+0xf3c/0x1930\n    [<000000007bf15a5f>] do_mount+0xf3/0x110\n    ...\n\nFix this by always setting is_root and NI_FLAG_DIR together.",
