Ubuntu Security Notice USN-7609-3
July 04, 2025

linux-ibm vulnerabilities
==========================================================================

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

- Ubuntu 24.04 LTS

Summary:

Several security issues were fixed in the Linux kernel.

Software Description:
- linux-ibm: Linux kernel for IBM 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:
   - InfiniBand drivers;
   - Netfilter;
   - Network traffic control;
(CVE-2025-38001, CVE-2025-37798, CVE-2025-37932, CVE-2025-37997,
CVE-2025-38000, CVE-2025-22088, CVE-2025-37890)

Update instructions:

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

Ubuntu 24.04 LTS
   linux-image-6.8.0-1028-ibm      6.8.0-1028.28
   linux-image-ibm                 6.8.0-1028.28
   linux-image-ibm-6.8             6.8.0-1028.28
   linux-image-ibm-classic         6.8.0-1028.28
   linux-image-ibm-lts-24.04       6.8.0-1028.28

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.
