Ubuntu Security Notice USN-7322-1
March 05, 2025

linux, 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: Linux 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:
  - Block layer subsystem;
  - Networking core;
(CVE-2024-56672, CVE-2024-56658)

Update instructions:

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

Ubuntu 24.10
  linux-image-6.11.0-19-generic   6.11.0-19.19
  linux-image-6.11.0-19-generic-64k  6.11.0-19.19
  linux-image-generic             6.11.0-19.19
  linux-image-generic-64k         6.11.0-19.19
  linux-image-virtual             6.11.0-19.19

Ubuntu 24.04 LTS
  linux-image-6.11.0-1016-oem     6.11.0-1016.16
  linux-image-oem-24.04b          6.11.0-1016.16

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.
