linux-nvidia-tegra 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-nvidia-tegra: Linux kernel for NVIDIA Tegra 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:
- Network drivers;
- NVME drivers;
- Netfilter;
(CVE-2026-23112, CVE-2026-23231, CVE-2026-23273)

Update instructions:

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

Ubuntu 24.04 LTS
linux-image-6.8.0-1023-nvidia-tegra 6.8.0-1023.23
linux-image-6.8.0-1023-nvidia-tegra-rt 6.8.0-1023.23
linux-image-nvidia-tegra 6.8.0-1023.23
linux-image-nvidia-tegra-6.8 6.8.0-1023.23
linux-image-nvidia-tegra-rt 6.8.0-1023.23
linux-image-nvidia-tegra-rt-6.8 6.8.0-1023.23

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.
