Ubuntu Security Notice USN-6864-1
July 04, 2024

linux-gcp, linux-intel 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-gcp: Linux kernel for Google Cloud Platform (GCP) systems
- linux-intel: Linux kernel for Intel IoT platforms

Details:

It was discovered that the Intel Data Streaming and Intel Analytics
Accelerator drivers in the Linux kernel allowed direct access to the
devices for unprivileged users and virtual machines. A local attacker could
use this to cause a denial of service. (CVE-2024-21823)

A security issue was discovered in the Linux kernel.
An attacker could possibly use it to compromise the system.
This update corrects flaws in the following subsystem:
   - Netfilter;
(CVE-2024-26924)

Update instructions:

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

Ubuntu 24.04 LTS
   linux-image-6.8.0-1006-intel    6.8.0-1006.13
   linux-image-6.8.0-1009-gcp      6.8.0-1009.10
   linux-image-gcp                 6.8.0-1009.10
   linux-image-intel               6.8.0-1006.13

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.
