Google: sys-kernel/cchost-kernel-6_12, sys-kernel/csql-kernel-6_12, sys-kernel/lakitu-kernel-6_12, sys-kernel/lakitu-nc-kernel-6_12: security update to 19506.448.8

critical Tenable Cloud Security Plugin ID 469684

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: add depth limit to
indx_find_buffer to prevent stack overflow indx_find_buffer() recursively descends the B+ tree index with
no depth limit. A crafted NTFS image with circular index node references causes unbounded recursion,
overflowing the kernel stack and panicking the system. This is reachable by mounting a malicious NTFS
filesystem (e.g. from a USB drive via desktop automount) and deleting a file whose index entry triggers
the rebalancing fallback path in indx_delete_entry(). Add a depth parameter and bail out with -EINVAL when
it reaches the fnd->nodes array bound, matching the constraint already enforced by fnd_push() in
indx_find(). The related function indx_find() was previously patched for a similar infinite-loop issue
(commit 1732053c8a6b), but indx_find_buffer() was missed. (CVE-2026-72194)

Solution

Update the sys-kernel/cchost-kernel-6_12 library and its related packages to version 19506.448.8 or later.
