Zeng Heng c58ea97aa9 fs/ntfs3: Fix slab-out-of-bounds read in hdr_delete_de()
[ Upstream commit ab84eee4c7 ]

Here is a BUG report from syzbot:

BUG: KASAN: slab-out-of-bounds in hdr_delete_de+0xe0/0x150 fs/ntfs3/index.c:806
Read of size 16842960 at addr ffff888079cc0600 by task syz-executor934/3631

Call Trace:
 memmove+0x25/0x60 mm/kasan/shadow.c:54
 hdr_delete_de+0xe0/0x150 fs/ntfs3/index.c:806
 indx_delete_entry+0x74f/0x3670 fs/ntfs3/index.c:2193
 ni_remove_name+0x27a/0x980 fs/ntfs3/frecord.c:2910
 ntfs_unlink_inode+0x3d4/0x720 fs/ntfs3/inode.c:1712
 ntfs_rename+0x41a/0xcb0 fs/ntfs3/namei.c:276

Before using the meta-data in struct INDEX_HDR, we need to
check index header valid or not. Otherwise, the corruptedi
(or malicious) fs image can cause out-of-bounds access which
could make kernel panic.

Fixes: 82cae269cf ("fs/ntfs3: Add initialization of super block")
