==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 25.04
- Ubuntu 24.04 LTS
Summary:
A security issue was fixed in the Linux kernel.
Software Description:
- linux: Linux kernel

- linux-realtime: Linux kernel for Real-time systems
- linux-aws-6.14: Linux kernel for Amazon Web Services (AWS) systems
- linux-gcp-6.14: Linux kernel for Google Cloud Platform (GCP) systems
- linux-hwe-6.14: Linux hardware enablement (HWE) kernel
- linux-oem-6.14: Linux kernel for OEM 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:

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.
