Ubuntu Security Notice USN-6873-1
July 04, 2024

linux-aws, linux-aws-6.5, linux-oem-6.5, linux-oracle, linux-oracle-6.5,
linux-starfive vulnerabilities
==========================================================================

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

- Ubuntu 23.10
- Ubuntu 22.04 LTS

Summary:

Several security issues were fixed in the Linux kernel.

Software Description:
- linux-aws: Linux kernel for Amazon Web Services (AWS) systems
- linux-oracle: Linux kernel for Oracle Cloud systems
- linux-starfive: Linux kernel for StarFive processors
- linux-aws-6.5: Linux kernel for Amazon Web Services (AWS) systems
- linux-oem-6.5: Linux kernel for OEM systems
- linux-oracle-6.5: Linux kernel for Oracle Cloud systems

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)

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 subsystem:
- Netfilter;
(CVE-2024-26643, CVE-2024-26925, CVE-2024-26924, CVE-2024-26809)

Update instructions:

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

Ubuntu 23.10
linux-image-6.5.0-1016-starfive 6.5.0-1016.17
linux-image-6.5.0-1022-aws 6.5.0-1022.22

linux-image-6.5.0-1025-oracle-64k 6.5.0-1025.25
linux-image-aws 6.5.0.1022.22
linux-image-oracle 6.5.0.1025.27
linux-image-oracle-64k 6.5.0.1025.27
linux-image-starfive 6.5.0.1016.18

Ubuntu 22.04 LTS
linux-image-6.5.0-1022-aws 6.5.0-1022.22~22.04.1
linux-image-6.5.0-1025-oem 6.5.0-1025.26
linux-image-6.5.0-1025-oracle 6.5.0-1025.25~22.04.1
linux-image-6.5.0-1025-oracle-64k 6.5.0-1025.25~22.04.1
linux-image-aws 6.5.0.1022.22~22.04.1
linux-image-oem-22.04 6.5.0.1025.27
linux-image-oem-22.04a 6.5.0.1025.27
linux-image-oem-22.04b 6.5.0.1025.27
linux-image-oem-22.04c 6.5.0.1025.27
linux-image-oem-22.04d 6.5.0.1025.27
linux-image-oracle 6.5.0.1025.25~22.04.1
linux-image-oracle-64k 6.5.0.1025.25~22.04.1

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.
