Releases

- linux-gcp-5.15 - Linux kernel for Google Cloud Platform (GCP) systems
- linux-gke - Linux kernel for Google Container Engine (GKE) systems
Details
Attila Szász discovered that the HFS+ file system implementation in the
Linux Kernel contained a heap overflow vulnerability. An attacker could use
a specially crafted file system image that, when mounted, could cause a
denial of service (system crash) or possibly execute arbitrary code.
(CVE-2025-0927)
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:
- Block layer subsystem;
- Network drivers;
(CVE-2024-50274, CVE-2024-53064, CVE-2024-56672)
Update instructions
The problem can be corrected by updating your system to the following package versions:
Ubuntu 22.04
-
linux-image-5.15.0-1076-gke
-
5.15.0-1076.82
-
linux-image-5.15.0-1078-gcp
-
5.15.0-1078.87
-
linux-image-gcp-lts-22.04
-
5.15.0.1078.74
-
linux-image-gke
-
5.15.0.1076.75
-
linux-image-gke-5.15
-
5.15.0.1076.75
Ubuntu 20.04
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.
