Preface: To enter UEFI Management mode on a Jetson device, you’ll typically need to access it during the boot process by pressing a specific key (like F2, F10, or Del) before the OS starts loading. Once in UEFI, you can configure settings related to booting, such as boot order and device selection.
Background: CUDA is a parallel computing platform and programming model developed by NVIDIA, designed to leverage the power of GPUs for general-purpose computing. Linux for Tegra (L4T) is NVIDIA’s customized Linux distribution based on Ubuntu, optimized for their Tegra family of system-on-chips (SoCs), including those used in Jetson development kits. Essentially, L4T provides the operating system and necessary drivers for running CUDA-enabled applications on NVIDIA’s embedded platforms.
NVIDIA Jetson Linux is a customized version of the Linux operating system specifically designed for NVIDIA Jetson embedded computing modules. It provides a complete software stack, including the Linux kernel, bootloader, drivers, and libraries, tailored for the Jetson platform’s hardware and intended for edge AI and robotics applications.
Vulnerability details:
CVE-2025-23270 NVIDIA Jetson Linux contains a vulnerability in UEFI Management mode, where an unprivileged local attacker may cause exposure of sensitive information via a side channel vulnerability. A successful exploit of this vulnerability might lead to code execution, data tampering, denial of service, and information disclosure.
CVE-2025-23269 NVIDIA Jetson Linux contains a vulnerability in the kernel where an attacker may cause an exposure of sensitive information due to a shared microarchitectural predictor state that influences transient execution. A successful exploit of this vulnerability may lead to information disclosure.
