linux-lowlatency, linux-oem-6.11 vulnerabilities
==========================================================================

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

- Ubuntu 24.10
- Ubuntu 24.04 LTS

Summary:

Several security issues were fixed in the Linux kernel.

Software Description:
- linux-lowlatency: Linux low latency kernel
- linux-oem-6.11: 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:
   - Netfilter;
   - Network traffic control;
(CVE-2025-38001, CVE-2025-37997, CVE-2025-37798, CVE-2025-38000,
CVE-2025-37932, CVE-2025-37890)

Update instructions:

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

Ubuntu 24.10
   linux-image-6.11.0-1016-lowlatency  6.11.0-1016.17
   linux-image-6.11.0-1016-lowlatency-64k  6.11.0-1016.17
   linux-image-lowlatency          6.11.0-1016.17
   linux-image-lowlatency-6.11     6.11.0-1016.17
   linux-image-lowlatency-64k      6.11.0-1016.17
   linux-image-lowlatency-64k-6.11  6.11.0-1016.17

Ubuntu 24.04 LTS
   linux-image-6.11.0-1025-oem     6.11.0-1025.25
   linux-image-oem-24.04b          6.11.0-1025.25
   linux-image-oem-6.11            6.11.0-1025.25

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.
