Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- 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.
[[email protected]: original patch contained changes to the problem already
handled, applied partly] (CVE-2026-89615)

Solution

Update the sys-kernel/cchost-kernel-6_12 library and its related packages to version 19506.505.8 or later.
