==========================================================================
Ubuntu Security Notice USN-7325-3
March 13, 2025

linux-nvidia-6.8, linux-nvidia-lowlatency vulnerabilities
==========================================================================

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

- Ubuntu 24.04 LTS
- Ubuntu 22.04 LTS

Summary:

Several security issues were fixed in the Linux kernel.

Software Description:
- linux-nvidia-lowlatency: Linux low latency kernel for NVIDIA systems
- linux-nvidia-6.8: Linux kernel for NVIDIA systems

Details:

Attila Szász discovered that the HFS+ file system implementation in the
Linux Kernel contained a heap overflow vulnerability. An attacker could use
a specially crafted file system image that, when mounted, could cause a
denial of service (system crash) or possibly execute arbitrary code.
(CVE-2025-0927)

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:
- Media drivers;
(CVE-2024-53104)

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-lowlatency 6.8.0-1023.26.1
linux-image-6.8.0-1023-nvidia-lowlatency-64k 6.8.0-1023.26.1
linux-image-nvidia-lowlatency 6.8.0-1023.26.1
linux-image-nvidia-lowlatency-64k 6.8.0-1023.26.1

Ubuntu 22.04 LTS
linux-image-6.8.0-1023-nvidia 6.8.0-1023.26~22.04.1
linux-image-6.8.0-1023-nvidia-64k 6.8.0-1023.26~22.04.1
linux-image-nvidia-6.8 6.8.0-1023.26~22.04.1
linux-image-nvidia-64k-6.8 6.8.0-1023.26~22.04.1
linux-image-nvidia-64k-hwe-22.04 6.8.0-1023.26~22.04.1
linux-image-nvidia-hwe-22.04 6.8.0-1023.26~22.04.1

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.
