Essential updates rectify several security flaws in the Linux kernel on Google Cloud Platform for Ubuntu as of February 14, 2024.
Several security issues were fixed in the Linux kernel.

Summary

Several security issues were fixed in the Linux kernel.

Software Description:

- linux-gcp-6.2: Linux kernel for Google Cloud Platform (GCP) systems

Details:

It was discovered that the USB subsystem in the Linux kernel contained a

race condition while handling device descriptors in certain situations,

leading to a out-of-bounds read vulnerability. A local attacker could

possibly use this to cause a denial of service (system crash).

(CVE-2023-37453)

Lucas Leong discovered that the netfilter subsystem in the Linux kernel did

not properly validate some attributes passed from userspace. A local

attacker could use this to cause a denial of service (system crash) or

possibly expose sensitive information (kernel memory). (CVE-2023-39189)

Sunjoo Park discovered that the netfilter subsystem in the Linux kernel did

not properly validate u32 packets content, leading to an out-of-bounds read

vulnerability. A local attacker could use this to cause a denial of service

Update Instructions

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 22.04 LTS:
  linux-image-6.2.0-1021-gcp      6.2.0-1021.23~22.04.1
  linux-image-gcp                 6.2.0.1021.23~22.04.1

After a standard system update you need to reboot your computer to make
all the necessary changes.

ATTENTION: Due to an unavoidable ABI change the kernel updates have
been given a new version number, which requires you to recompile and
reinstall all third party kernel modules you might have installed.
Unless you manually uninstalled the standard kernel metapackages
(e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual,
linux-powerpc), a standard system upgrade will automatically perform
this as well.
