Google: sys-kernel/lakitu-kernel-6_1: security update to 17872.0.0

high Tenable Cloud Security Plugin ID 451393

Description

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

- A use-after-free vulnerability in the Linux kernel's net/sched: cls_u32 component can be exploited to
achieve local privilege escalation. When u32_change() is called on an existing filter, the whole
tcf_result struct is always copied into the new instance of the filter. This causes a problem when
updating a filter bound to a class, as tcf_unbind_filter() is always called on the old instance in the
success path, decreasing filter_cnt of the still referenced class and allowing it to be deleted, leading
to a use-after-free. We recommend upgrading past commit 3044b16e7c6fe5d24b1cdbcf1bd0a9d92d1ebd81.
(CVE-2023-4208)

Solution

Update the sys-kernel/lakitu-kernel-6_1 library and its related packages to version 17872.0.0 or later.
