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

fs/ntfs3: bound page_lcns[] index by the log record

The copy_lcns loop and the redo shorten loop index page_lcns[] at j + i,
where i runs up to the log record's lcns_follow. That count is checked only
against the record's own length, not the target entry, so check_dp_table()
(which validates the entry's lcns_follow) does not cover it: the copy_lcns
entry may even be freshly allocated after that check, and find_dp() bounds j
but not i. A crafted record thus overflows page_lcns[] of an otherwise valid
entry.

Add dp_range_ok() and reject, before each loop, any record whose run does
not fit the entry. These are the only two page_lcns[] accesses indexed by
the record rather than the entry, so together with the entry validation
every access is now bounded.
