Google: sys-kernel/lakitu-kernel-6_1: security update to 18026.0.0

medium Tenable Cloud Security Plugin ID 451845

Description

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

- Closing of an event channel in the Linux kernel can result in a deadlock. This happens when the close is
being performed in parallel to an unrelated Xen console action and the handling of a Xen console interrupt
in an unprivileged guest. The closing of an event channel is e.g. triggered by removal of a paravirtual
device on the other side. As this action will cause console messages to be issued on the other side quite
often, the chance of triggering the deadlock is not neglectable. Note that 32-bit Arm-guests are not
affected, as the 32-bit Linux kernel on Arm doesn't use queued-RW-locks, which are required to trigger the
issue (on Arm32 a waiting writer doesn't block further readers to get the lock). (CVE-2023-34324)

Solution

Update the sys-kernel/lakitu-kernel-6_1 library and its related packages to version 18026.0.0 or later.
