Linux kernel updates for Ubuntu

Ubuntu 7045 Published by

Two Ubuntu security notices released address critical Linux kernel vulnerabilities across multiple distributions. The first notice targets newer systems on versions like 25.10 and 24.04 LTS, patching flaws in Oracle Cloud and Raspberry Pi kernels involving network traffic control and cryptographic APIs. A separate notice covers older systems running Ubuntu 22.04 or 20.04 where ARM64 flaws are fixed alongside those other network security issues. Users must reboot their systems because kernel modules from third parties will require recompilation due to unavoidable application binary interface changes.

[USN-8149-2] Linux kernel vulnerabilities


==========================================================================
Ubuntu Security Notice USN-8149-2
April 09, 2026

linux-oracle, linux-oracle-6.17, linux-raspi vulnerabilities
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 25.10
- Ubuntu 24.04 LTS

Summary:

Several security issues were fixed in the Linux kernel.

Software Description:
- linux-oracle: Linux kernel for Oracle Cloud systems
- linux-raspi: Linux kernel for Raspberry Pi systems
- linux-oracle-6.17: Linux kernel for Oracle Cloud 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:
- Cryptographic API;
- Netfilter;
- Network traffic control;
(CVE-2026-23060, CVE-2026-23074, CVE-2026-23111)

Update instructions:

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

Ubuntu 25.10
linux-image-6.17.0-1010-oracle 6.17.0-1010.10
linux-image-6.17.0-1010-oracle-64k 6.17.0-1010.10
linux-image-6.17.0-1011-raspi 6.17.0-1011.11
linux-image-oracle 6.17.0-1010.10
linux-image-oracle-6.17 6.17.0-1010.10
linux-image-oracle-64k 6.17.0-1010.10
linux-image-oracle-64k-6.17 6.17.0-1010.10
linux-image-raspi 6.17.0-1011.11
linux-image-raspi-6.17 6.17.0-1011.11

Ubuntu 24.04 LTS
linux-image-6.17.0-1010-oracle 6.17.0-1010.10~24.04.1
linux-image-6.17.0-1010-oracle-64k 6.17.0-1010.10~24.04.1
linux-image-oracle 6.17.0-1010.10~24.04.1
linux-image-oracle-6.17 6.17.0-1010.10~24.04.1
linux-image-oracle-64k 6.17.0-1010.10~24.04.1
linux-image-oracle-64k-6.17 6.17.0-1010.10~24.04.1

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.

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.
