Google: sys-kernel/csql-kernel-6_1, sys-kernel/lakitu-kernel-6_1: security update to 18244.448.6

medium Tenable Cloud Security Plugin ID 452455

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: kernfs: Relax constraint in draining
guard The active reference lifecycle provides the break/unbreak mechanism but the active reference is not
truly active after unbreak -- callers don't use it afterwards but it's important for proper pairing of
kn->active counting. Assuming this mechanism is in place, the WARN check in
kernfs_should_drain_open_files() is too sensitive -- it may transiently catch those (rightful) callers
between kernfs_unbreak_active_protection() and kernfs_put_active() as found out by Chen Ridong:
kernfs_remove_by_name_ns kernfs_get_active // active=1 __kernfs_remove // active=0x80000002 kernfs_drain
... wait_event //waiting (active == 0x80000001) kernfs_break_active_protection // active = 0x80000001 //
continue kernfs_unbreak_active_protection // active = 0x80000002 ... kernfs_should_drain_open_files //
warning occurs kernfs_put_active To avoid the false positives (mind panic_on_warn) remove the check
altogether. (This is meant as quick fix, I think active reference break/unbreak may be simplified with
larger rework.) (CVE-2025-38282)
