Doc Text:
A flaw was found in the `fs/ntfs3` module in the Linux kernel. This issue involved inadequate validation of the `ff` offset, which could lead to out-of-bounds reads if the offset was excessively large. This flaw posed risks of crashes and information leaks, and has been addressed by adding sanity checks to validate the `ff` offset before use, ensuring safer memory access and improving system stability.

Description OSIDB Bzimport 2024-07-29 07:21:31 UTC 
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.
