Ubuntu Security Notice USN-7829-5
October 28, 2025

linux-intel-iotg, linux-intel-iotg-5.15 vulnerabilities
==========================================================================

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

- Ubuntu 22.04 LTS
- Ubuntu 20.04 LTS

Summary:

Several security issues were fixed in the Linux kernel.

Software Description:
- linux-intel-iotg: Linux kernel for Intel IoT platforms
- linux-intel-iotg-5.15: Linux kernel for Intel IoT platforms

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:
- GPU drivers;
- Network drivers;
- Netlink;
(CVE-2024-26700, CVE-2025-38727, CVE-2023-52593, CVE-2024-26896)

Update instructions:

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

Ubuntu 22.04 LTS
linux-image-5.15.0-1090-intel-iotg 5.15.0-1090.96
linux-image-intel-iotg 5.15.0.1090.90
linux-image-intel-iotg-5.15 5.15.0.1090.90

Ubuntu 20.04 LTS
linux-image-5.15.0-1090-intel-iotg 5.15.0-1090.96~20.04.1
Available with Ubuntu Pro
linux-image-intel 5.15.0.1090.96~20.04.1
Available with Ubuntu Pro
linux-image-intel-iotg 5.15.0.1090.96~20.04.1
Available with Ubuntu Pro
linux-image-intel-iotg-5.15 5.15.0.1090.96~20.04.1
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.
