Ubuntu Security Notice USN-7492-2
May 06, 2025

linux-realtime vulnerability
==========================================================================

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

- Ubuntu 24.04 LTS

Summary:

The system could be made to crash or run programs as an administrator.

Software Description:
- linux-realtime: Linux kernel for Real-time systems

Details:

A security issue was discovered in the Linux kernel.
An attacker could possibly use this to compromise the system.
This update corrects flaws in the following subsystems:
  - Bluetooth drivers;
(CVE-2024-56653)

Update instructions:

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

Ubuntu 24.04 LTS
  linux-image-6.8.1-1021-realtime  6.8.1-1021.22
                                  Available with Ubuntu Pro
  linux-image-realtime            6.8.1-1021.22
                                  Available with Ubuntu Pro
  linux-image-realtime-hwe-24.04  6.8.1-1021.22
                                  Available with Ubuntu Pro

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.
