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

high Tenable Cloud Security Plugin ID 451847

Description

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

- An issue was discovered in the Linux kernel before 6.5.9, exploitable by local users with userspace access
to MMIO registers. Incorrect access checking in the #VC handler and instruction emulation of the SEV-ES
emulation of MMIO accesses could lead to arbitrary write access to kernel memory (and thus privilege
escalation). This depends on a race condition through which userspace can replace an instruction before
the #VC handler reads it. (CVE-2023-46813)

Solution

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