Ubuntu Security Notice USN-8622-1
July 29, 2026

linux-nvidia, linux-nvidia-7.0 vulnerabilities
==========================================================================

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

- Ubuntu 26.04 LTS
- Ubuntu 24.04 LTS

Summary:

Several security issues were fixed in the Linux kernel.

Software Description:
- linux-nvidia: Linux kernel for NVIDIA systems
- linux-nvidia-7.0: Linux kernel for NVIDIA 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:
  - ARM64 architecture;
  - Arm Firmware Framework for ARMv8-A(FFA);
(CVE-2026-53354, CVE-2026-64520)

Update instructions:

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

Ubuntu 26.04 LTS
  linux-image-7.0.0-1015-nvidia   7.0.0-1015.15
  linux-image-7.0.0-1015-nvidia-64k  7.0.0-1015.15
  linux-image-nvidia              7.0.0-1015.15
  linux-image-nvidia-64k          7.0.0-1015.15
  linux-image-nvidia-64k-7.0      7.0.0-1015.15
  linux-image-nvidia-7.0          7.0.0-1015.15

Ubuntu 24.04 LTS
  linux-image-7.0.0-1015-nvidia   7.0.0-1015.15~24.04.1
  linux-image-7.0.0-1015-nvidia-64k  7.0.0-1015.15~24.04.1
  linux-image-nvidia-64k-7.0      7.0.0-1015.15~24.04.1
  linux-image-nvidia-7.0          7.0.0-1015.15~24.04.1

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.
