Ubuntu Security Notice USN-8659-3
August 25, 2026

linux-azure, linux-azure-fde vulnerability
==========================================================================

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

- Ubuntu 26.04 LTS

Summary:

A security issue was fixed in the Linux kernel.

Software Description:
- linux-azure: Linux kernel for Microsoft Azure Cloud systems
- linux-azure-fde: Linux kernel for Microsoft Azure CVM cloud systems

Details:

A security issue was discovered in the Linux kernel.
An attacker could possibly use this to compromise the system.
This update corrects flaws in the following subsystems:
   - Open vSwitch;

Update instructions:

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

Ubuntu 26.04 LTS
   linux-image-7.0.0-1011-azure-fde  7.0.0-1011.11
   linux-image-7.0.0-1012-azure    7.0.0-1012.12
   linux-image-azure               7.0.0-1012.12
   linux-image-azure-7.0           7.0.0-1012.12
   linux-image-azure-fde           7.0.0-1011.11
   linux-image-azure-fde-7.0       7.0.0-1011.11
   linux-image-azure-fde-lts-26.04  7.0.0-1011.11
   linux-image-azure-lts-26.04     7.0.0-1012.12

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.
