Summary
fs/ntfs3: Fix an NULL dereference bug
Details

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

fs/ntfs3: Fix an NULL dereference bug

The issue here is when this is called from ntfsloadattrlist(). The "size" comes from le32tocpu(attr->res.datasize) so it can't overflow on a 64bit systems but on 32bit systems the "+ 1023" can overflow and the result is zero. This means that the kmalloc will succeed by returning the ZEROSIZEPTR and then the memcpy() will crash with an Oops on the next line.
