Ubuntu Security Notice USN-7833-2
October 22, 2025
linux-realtime-6.14 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-realtime-6.14: Linux kernel for Real-time systems
Details:
Oleksii Oleksenko, Cedric Fournet, Jana Hofmann, Boris Köpf, Stavros Volos,
and Flavien Solt discovered that some AMD processors may allow an attacker
to infer data from previous stores, potentially resulting in the leakage of
privileged information. A local attacker could possibly use this to expose
sensitive information. (CVE-2024-36350, CVE-2024-36357)
Several security issues were discovered in the Linux kernel.
An attacker could possibly use these to compromise the system.

Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 24.04 LTS
linux-image-6.14.0-1014-realtime 6.14.0-1014.14~24.04.1
Available with Ubuntu Pro
linux-image-realtime-6.14 6.14.0-1014.14~24.04.1
Available with Ubuntu Pro
linux-image-realtime-hwe-24.04 6.14.0-1014.14~24.04.1
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.
