linux-realtime, 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
- linux-realtime: Linux kernel for Real-time systems

Details:

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 22.04 LTS
   linux-image-5.15.0-1073-intel-iot-realtime  5.15.0-1073.75
   linux-image-5.15.0-1080-realtime  5.15.0-1080.88
   linux-image-intel-iot-realtime  5.15.0.1073.77
   linux-image-realtime            5.15.0.1080.83

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.
