Ubuntu Security Notice USN-8659-4
August 26, 2026

linux-oracle 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-oracle: Linux kernel for Oracle 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-7.0.0-1010-oracle   7.0.0-1010.10
   linux-image-7.0.0-1010-oracle-64k  7.0.0-1010.10
   linux-image-oracle              7.0.0-1010.10
   linux-image-oracle-64k          7.0.0-1010.10
   linux-image-oracle-64k-7.0      7.0.0-1010.10
   linux-image-oracle-7.0          7.0.0-1010.10

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.
