CVE-2021-34374: Trusty contains a vulnerability in command handlers where the length of input buffers is not verified.

Trusty contains a vulnerability in command handlers where the length of input buffers is not verified. This vulnerability can cause memory corruption, which may lead to information disclosure, escalation of privileges, and denial of service.

Security readout for executives and security teams

Plain-English summary

This flaw affects specific NVIDIA Jetson devices running Jetson Linux before r32.5.1. A local, highly privileged attacker who can trigger the vulnerable Trusty command handlers may cause memory corruption, potentially exposing data, gaining more privilege, or disrupting the device.

Executive priority

Treat this as a high-priority remediation item for affected Jetson fleets, especially in production, robotics, edge AI, or physical operations. It is not described as remotely exploitable or actively exploited in the provided sources.

Technical view

Trusty command handlers do not verify input buffer lengths, allowing memory corruption. The CVSS 3.1 vector is local attack, low complexity, high privileges required, user interaction required, changed scope, and high confidentiality, integrity, and availability impact.

Likely exposure

Exposure is limited to NVIDIA Jetson AGX Xavier series, Jetson Xavier NX, Jetson TX2 series, and Jetson TX2 NX on Jetson Linux versions prior to r32.5.1.

Exploitation context

The source bundle does not show KEV listing or confirmed active exploitation. The CVSS vector indicates exploitation requires local access, high privileges, and user interaction, which reduces broad remote risk but remains serious on shared or operational devices.

Researcher notes

Evidence is limited to the CVE record, CVE List entry, and NVIDIA advisory reference. Do not assume additional Jetson models, Trusty deployments, public exploit availability, or fixes beyond moving from versions prior to r32.5.1.

Mitigation direction

  • Upgrade affected Jetson Linux installations to r32.5.1 or later where supported.
  • Review NVIDIA advisory 5205 for product-specific update guidance.
  • Restrict local administrative access to affected Jetson devices.
  • Prioritize operational devices where disclosure, privilege escalation, or denial of service would disrupt services.

Validation and detection

  • Inventory Jetson AGX Xavier, Xavier NX, TX2 series, and TX2 NX devices.
  • Confirm each device is not running Jetson Linux prior to r32.5.1.
  • Check vulnerability records against the CVSS vector and affected product list.
  • Document any devices that cannot be upgraded and track vendor guidance.
