Google: sys-kernel/lakitu-kernel-6_1, sys-kernel/lakitu-kernel-6_6: security update to 18613.0.3

medium Tenable Self-Hosted Container Security Plugin ID 471565

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: mm/mglru: fix div-by-zero in
vmpressure_calc_level() evict_folios() uses a second pass to reclaim folios that have gone through page
writeback and become clean before it finishes the first pass, since folio_rotate_reclaimable() cannot
handle those folios due to the isolation. The second pass tries to avoid potential double counting by
deducting scan_control->nr_scanned. However, this can result in underflow of nr_scanned, under a condition
where shrink_folio_list() does not increment nr_scanned, i.e., when folio_trylock() fails. The underflow
can cause the divisor, i.e., scale=scanned+reclaimed in vmpressure_calc_level(), to become zero, resulting
in the following crash: [exception RIP: vmpressure_work_fn+101] process_one_work at ffffffffa3313f2b Since
scan_control->nr_scanned has no established semantics, the potential double counting has minimal risks.
Therefore, fix the problem by not deducting scan_control->nr_scanned in evict_folios(). (CVE-2024-42316)

Solution

Update the sys-kernel/lakitu-kernel-6_1 library and its related packages to version 18613.0.3 or later.
