USN-7326-1: Linux kernel vulnerabilities
5 March 2025

Several security issues were fixed in the Linux kernel.

Releases
Ubuntu 24.04 LTS Ubuntu 22.04 LTS

Packages

• linux-gcp - Linux kernel for Google Cloud Platform (GCP) systems
• linux-gcp-6.8 - Linux kernel for Google Cloud Platform (GCP) systems
• linux-gke - Linux kernel for Google Container Engine (GKE) systems
• linux-gkeop - 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:

Media drivers;
Network drivers;
(CVE-2024-50274, CVE-2024-53104, CVE-2024-53064)

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

• linux-image-gcp-64k - 6.8.0-1025.27~22.04.1
  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.
