Ubuntu Security Notice USN-7879-3
November 26, 2025

linux-aws-6.14, linux-oracle-6.14 vulnerabilities
==========================================================================

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

- Ubuntu 24.04 LTS

Summary:

Several security issues were fixed in the Linux kernel.

Software Description:
- linux-aws-6.14: Linux kernel for Amazon Web Services (AWS) systems
- linux-oracle-6.14: Linux kernel for Oracle Cloud systems

Details:

It was discovered that improper initialization of CPU cache memory could
allow a local attacker with hypervisor access to overwrite SEV-SNP guest
memory resulting in loss of data integrity. (CVE-2024-36331)

Several security issues were discovered in the Linux kernel.
An attacker could possibly use these to compromise the system.

CVE-2025-39809, CVE-2025-39818, CVE-2025-40157)

Update instructions:

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

Ubuntu 24.04 LTS
  linux-image-6.14.0-1017-aws     6.14.0-1017.17~24.04.1
  linux-image-6.14.0-1017-aws-64k  6.14.0-1017.17~24.04.1
  linux-image-6.14.0-1017-oracle  6.14.0-1017.17~24.04.1
  linux-image-6.14.0-1017-oracle-64k  6.14.0-1017.17~24.04.1
  linux-image-aws                 6.14.0-1017.17~24.04.1
  linux-image-aws-6.14            6.14.0-1017.17~24.04.1
  linux-image-aws-64k             6.14.0-1017.17~24.04.1
  linux-image-aws-64k-6.14        6.14.0-1017.17~24.04.1
  linux-image-oracle              6.14.0-1017.17~24.04.1
  linux-image-oracle-6.14         6.14.0-1017.17~24.04.1
  linux-image-oracle-64k          6.14.0-1017.17~24.04.1
  linux-image-oracle-64k-6.14     6.14.0-1017.17~24.04.1

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.

security advisory Ubuntu local access data integrity Linux kernel hypervisor

Update Instructions

The problem can be corrected by updating your system to the following package versions: Ubuntu 24.04 LTS linux-image-6.14.0-1017-aws 6.14.0-1017.17~24.04.1 linux-image-6.14.0-1017-aws-64k 6.14.0-1017.17~24.04.1 linux-image-6.14.0-1017-oracle 6.14.0-1017.17~24.04.1 linux-image-6.14.0-1017-oracle-64k 6.14.0-1017.17~24.04.1 linux-image-aws 6.14.0-1017.17~24.04.1 linux-image-aws-6.14 6.14.0-1017.17~24.04.1 linux-image-aws-64k 6.14.0-1017.17~24.04.1 linux-image-aws-64k-6.14 6.14.0-1017.17~24.04.1 linux-image-oracle 6.14.0-1017.17~24.04.1 linux-image-oracle-6.14 6.14.0-1017.17~24.04.1 linux-image-oracle-64k 6.14.0-1017.17~24.04.1 linux-image-oracle-64k-6.14 6.14.0-1017.17~24.04.1 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.
