CVE-2025-33182
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedNVIDIA Jetson Linux contains a vulnerability in UEFI, where improper authentication may allow a privileged user to cause corruption of the Linux Device Tree. A successful exploitation of this vulnerability might lead to data tampering, denial of service.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceNVIDIA Jetson Linux contains an improper authentication vulnerability in UEFI that allows a privileged user to corrupt the Linux Device Tree, potentially leading to data tampering or denial of service. The Device Tree is critical hardware configuration data used during boot, and corruption can prevent proper hardware initialization or cause unpredictable system behavior.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify Jetson Linux versionRun 'cat /etc/nv_tegra_release' or check the L4T version with 'cat /etc/*release*' to determine the installed Jetson Linux versionAffected if The installed version is older than the patched version that addresses CVE-2025-33182
-
Verify UEFI firmware is in useCheck UEFI variables and boot configuration by examining /sys/firmware/efi directory or running 'efivar -l' if efivar-tools is installedAffected if UEFI is active as the boot firmware (which is the default on Jetson devices)
-
Inspect Device Tree blob integrityCompare the currently loaded Device Tree blob (found in /boot or /boot/dtb) against a known-good source or backup; use 'md5sum' or 'sha256sum' to verify file integrityAffected if The Device Tree blob (.dtb) file shows unexpected modification or differs from the expected hash
-
Check Device Tree source files for unauthorized changesReview Device Tree source files in /boot/bootloader/dtb/ or the kernel source tree; look for unexpected modifications to .dts/.dtsi files that could indicate tamperingAffected if Device Tree source files have been altered from their original state or contain unexpected entries
-
Assess secure boot statusCheck if UEFI secure boot is enabled by examining UEFI firmware settings or using 'mokutil --sb-state' if available on the Jetson platformAffected if Secure boot is disabled or not properly configured, allowing unsigned Device Tree modifications
A user is affected if running an unpatched Jetson Linux version with UEFI enabled and either compromised Device Tree files or secure boot disabled.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataApply NVIDIA-provided firmware updates for Jetson Linux that address the UEFI authentication weakness. Verify Device Tree integrity after updates and ensure secure boot configurations are enabled.
