27 February 2025

Overview

Several security issues were fixed in the Linux kernel.

Releases

Packages

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;
  • Block layer subsystem;
  • ACPI drivers;
  • Drivers core;
  • ATA over ethernet (AOE) driver;
  • TPM device driver;
  • GPIO subsystem;
  • GPU drivers;
  • HID subsystem;
  • I2C subsystem;
  • InfiniBand drivers;
  • Mailbox framework;
  • Multiple devices 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-5.4.0-1138-oracle –  5.4.0-1138.147
linux-image-5.4.0-1140-aws –  5.4.0-1140.150
linux-image-aws-lts-20.04 –  5.4.0.1140.137
linux-image-oracle-lts-20.04 –  5.4.0.1138.131
18.04 bionic linux-image-5.4.0-1138-oracle –  5.4.0-1138.147~18.04.1  
linux-image-oracle –  5.4.0.1138.147~18.04.1
