## Packages

* [linux-intel-iot-realtime](https://ubuntu.com/security/cves?package=linux-intel-iot-realtime) - Linux kernel for Intel IoT Real-time platforms
* [linux-realtime](https://ubuntu.com/security/cves?package=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.
This update corrects flaws in the following subsystems:

* TTY drivers;
* Network traffic control

## Update instructions

After a standard system update you need to reboot your computer to make
all the necessary changes.

[Learn more about how to get the fixes.](https://ubuntu.com/security/cves/about#security)

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.

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

| Ubuntu Release | Package Version |

| 22.04 LTS jammy | [linux-image-5.15.0-1082-intel-iot-realtime](https://launchpad.net/ubuntu/+source/linux-signed-intel-iot-realtime) –  5.15.0-1082.84   Real-time | | |
