Google: sys-kernel/lakitu-kernel-5_10, sys-kernel/lakitu-kernel-5_15: security update to 17148.0.0

medium Tenable Cloud Security Plugin ID 454442

Description

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

- Arm guests can cause Dom0 DoS via PV devices When mapping pages of guests on Arm, dom0 is using an rbtree
to keep track of the foreign mappings. Updating of that rbtree is not always done completely with the
related lock held, resulting in a small race window, which can be used by unprivileged guests via PV
devices to cause inconsistencies of the rbtree. These inconsistencies can lead to Denial of Service (DoS)
of dom0, e.g. by causing crashes or the inability to perform further mappings of other guests' memory
pages. (CVE-2022-33744)

Solution

Update the sys-kernel/lakitu-kernel-5_10 library and its related packages to version 17148.0.0 or later.
