Ubuntu Security Notice USN-7236-2
January 29, 2025

linux-lowlatency-hwe-6.8 vulnerabilities
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 22.04 LTS

Summary:

Several security issues were fixed in the Linux kernel.

Software Description:
- linux-lowlatency-hwe-6.8: Linux low latency kernel

Details:

Several security issues were discovered in the Linux kernel.
An attacker could possibly use these to compromise the system.
This update corrects flaws in the following subsystems:
- Netfilter;
- Network traffic control;
- VMware vSockets driver;
(CVE-2024-53164, CVE-2024-53103, CVE-2024-53141)

Update instructions:

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

Ubuntu 22.04 LTS
linux-image-6.8.0-52-lowlatency 6.8.0-52.53.1~22.04.1
linux-image-6.8.0-52-lowlatency-64k 6.8.0-52.53.1~22.04.1
linux-image-lowlatency-64k-hwe-22.04 6.8.0-52.53.1~22.04.1
linux-image-lowlatency-hwe-22.04 6.8.0-52.53.1~22.04.1

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.
