Description
In the Linux kernel, the following vulnerability has been resolved:
fs/ntfs3: Validate ff offset
This adds sanity checks for ff offset. There is a check
on rt->first_free at first, but walking through by ff
without any check. If the second ff is a large offset.
We may encounter an out-of-bound read.
