Ubuntu Security Notice USN-7072-2
October 21, 2024

linux-gke 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-gke: Linux kernel for Google Container Engine (GKE) systems

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:
- Watchdog drivers;
- Netfilter;
- Network traffic control;
(CVE-2024-38630, CVE-2024-27397, CVE-2024-45016)

Update instructions:

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

Ubuntu 22.04 LTS
linux-image-5.15.0-1068-gke 5.15.0-1068.74
linux-image-gke 5.15.0.1068.67
linux-image-gke-5.15 5.15.0.1068.67

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.
