linux-oracle vulnerability
=========================================================================
A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 25.04

Summary:

A security issue was fixed in the Linux kernel.

Software Description:
- linux-oracle: 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:
  - Network traffic control;
(CVE-2025-38083)

Update instructions:

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

Ubuntu 25.04
  linux-image-6.14.0-1010-oracle  6.14.0-1010.10
  linux-image-6.14.0-1010-oracle-64k  6.14.0-1010.10
  linux-image-oracle              6.14.0-1010.10
  linux-image-oracle-6.14         6.14.0-1010.10
  linux-image-oracle-64k          6.14.0-1010.10
  linux-image-oracle-64k-6.14     6.14.0-1010.10

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.
