Ubuntu Security Notice USN-8291-1
May 21, 2026

linux-intel-iot-realtime vulnerabilities
==========================================================================

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

- Ubuntu 22.04 LTS

Summary:

Several security issues were fixed in the Linux kernel.

Software Description:
- linux-intel-iot-realtime: Linux kernel for Intel IoT Real-time 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:
   - SMB network file system;
   - Netfilter;
   - io_uring subsystem;
(CVE-2024-35862, CVE-2024-50060, CVE-2026-23274, CVE-2026-23351)

Update instructions:

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

Ubuntu 22.04 LTS
   linux-image-5.15.0-1099-intel-iot-realtime  5.15.0-1099.101
                                   Available with Ubuntu Pro
   linux-image-intel-iot-realtime  5.15.0.1099.103
                                   Available with Ubuntu Pro
   linux-image-intel-iot-realtime-5.15  5.15.0.1099.103
                                   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.
