Google: sys-kernel/lakitu-kernel-5_10, sys-kernel/lakitu-kernel-5_15: security update to 17162.40.1

high Tenable Cloud Security Plugin ID 453930

Description

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

 - There exists a use-after-free in io_uring in the Linux kernel. Signalfd_poll() and binder_poll() use a
 waitqueue whose lifetime is the current task. It will send a POLLFREE notification to all waiters before
 the queue is freed. Unfortunately, the io_uring poll doesn't handle POLLFREE. This allows a use-after-free
 to occur if a signalfd or binder fd is polled with io_uring poll, and the waitqueue gets freed. We
 recommend upgrading past commit fc78b2fc21f10c4c9c4d5d659a685710ffa63659 (CVE-2022-3176)

Solution

Update the sys-kernel/lakitu-kernel-5_10 library and its related packages to version 17162.40.1 or later.
