linux-starfive-6.5 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-starfive-6.5: Linux kernel for StarFive processors
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 22.04 LTS
   linux-image-6.5.0-1016-starfive  6.5.0-1016.17~22.04.1
   linux-image-starfive            6.5.0.1016.17~22.04.1
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.
