Packages
- 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
-
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.
