Publication date

16 May 2025

Overview

Several security issues were fixed in the Linux kernel.

Releases

Packages

  • linux-gcp-5.15 - Linux kernel for Google Cloud Platform (GCP) 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:

  • ARM64 architecture;
  • PowerPC architecture;
  • x86 architecture;
  • Block layer subsystem;
  • Network block device driver;
  • Bus devices;
  • Character device driver;

Update instructions

After a standard system update you need to reboot your computer to make all the necessary changes.

Learn more about how to get the fixes.

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.

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

Ubuntu Release Package Version
20.04 focal linux-image-5.15.0-1083-gcp –  5.15.0-1083.92~20.04.1
linux-image-gcp –  5.15.0.1083.92~20.04.1
