Google: sys-kernel/lakitu-kernel-6_1: security update to 17908.0.0

high Tenable Self-Hosted Container Security Plugin ID 450482

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: sch_hfsc (HFSC qdisc traffic control)
 component can be exploited to achieve local privilege escalation. If a class with a link-sharing curve
 (i.e. with the HFSC_FSC flag set) has a parent without a link-sharing curve, then init_vf() will call
 vttree_insert() on the parent, but vttree_remove() will be skipped in update_vf(). This leaves a dangling
 pointer that can cause a use-after-free. We recommend upgrading past commit
 b3d26c5702c7d6c45456326e56d2ccf3f103e60f. (CVE-2023-4623)

Solution

Update the sys-kernel/lakitu-kernel-6_1 library and its related packages to version 17908.0.0 or later.
