CVE-2026-24148: NVIDIA Jetson Information Disclosure Flaw

CVE-2026-24148 Overview

NVIDIA Jetson for JetPack contains a vulnerability in the system initialization logic that allows an unprivileged attacker to cause the initialization of a resource with an insecure default configuration. This vulnerability affects the embedded AI platform widely used in robotics, autonomous machines, and edge computing applications.

A successful exploit of this vulnerability could lead to information disclosure of encrypted data, data tampering, and partial denial of service across devices sharing the same machine ID. The network-accessible nature of this vulnerability combined with low attack complexity makes it particularly concerning for deployed Jetson devices in production environments.

Critical Impact

Unprivileged attackers can exploit insecure default initialization to compromise encrypted data confidentiality, tamper with device data, and cause partial denial of service affecting multiple devices sharing the same machine ID.

Technical Details for CVE-2026-24148

Vulnerability Analysis

This vulnerability is classified under CWE-1188 (Insecure Default Initialization of Resource), indicating that a system resource is initialized with default values that create a security weakness. In the context of NVIDIA Jetson devices, the system initialization logic fails to properly secure resources during the boot or configuration process.

The vulnerability can be exploited over the network by an attacker with low privileges and requires no user interaction. When successfully exploited, the attacker gains the ability to access encrypted data that should remain confidential, modify data on the affected system, and cause service disruptions. The impact is amplified when multiple devices share the same machine ID, as a single exploit could potentially affect an entire fleet of Jetson devices.

Root Cause

The root cause of this vulnerability lies in the system initialization logic of NVIDIA Jetson for JetPack. During the initialization phase, certain resources are configured with insecure default values rather than being properly secured. This represents a fundamental secure-by-default design failure where the system does not enforce appropriate security constraints during the critical initialization process.

The insecure defaults likely relate to machine ID configuration, which when shared across devices, creates a lateral impact vector where compromising one device's initialization state affects the security posture of other devices in the same deployment.

Attack Vector

The attack vector for CVE-2026-24148 is network-based, allowing remote exploitation without physical access to the target Jetson device. An attacker needs only low-level privileges to execute the attack, and no user interaction is required for successful exploitation.

The attack proceeds by targeting the system initialization logic during or after the device boot process. By manipulating the initialization flow, an unprivileged attacker can force resources to be created or configured with insecure defaults, bypassing intended security controls. This can expose cryptographic material, enable data tampering capabilities, and disrupt normal device operations.

Detection Methods for CVE-2026-24148

Indicators of Compromise

• Unexpected changes to system initialization configurations or boot parameters on Jetson devices
• Anomalous access patterns to encrypted data or cryptographic resources
• Multiple devices exhibiting synchronized security anomalies due to shared machine ID exploitation
• Unauthorized modifications to system configuration files related to initialization logic

Detection Strategies

• Monitor system initialization logs for unauthorized or unexpected configuration changes during boot sequences
• Implement integrity monitoring for critical system resources that are initialized during device startup
• Deploy network-based detection rules to identify exploitation attempts targeting Jetson device initialization endpoints
• Audit machine ID configurations across device fleets to identify potentially vulnerable shared configurations

Monitoring Recommendations

• Enable verbose logging for system initialization processes on all deployed Jetson devices
• Implement centralized log collection from Jetson device fleets to correlate potential multi-device attacks
• Set up alerts for authentication or authorization anomalies occurring during or immediately after device initialization
• Monitor for data integrity violations that may indicate successful data tampering exploitation

How to Mitigate CVE-2026-24148

Immediate Actions Required

• Review the NVIDIA Support Answer #5797 security advisory for vendor-specific guidance and patches
• Conduct an inventory of all NVIDIA Jetson devices running JetPack to assess exposure
• Implement network segmentation to limit remote access to Jetson devices where possible
• Review and remediate any shared machine ID configurations across device deployments

Patch Information

NVIDIA has released a security advisory addressing this vulnerability. Organizations should consult the NVIDIA Support Answer #5797 for specific patch availability and installation instructions for affected JetPack versions. Apply vendor-provided updates as soon as they become available after appropriate testing in non-production environments.

Workarounds

• Restrict network access to Jetson devices using firewall rules or network segmentation until patches can be applied
• Implement additional authentication controls for access to system initialization functions
• Ensure each Jetson device uses a unique machine ID to prevent cross-device impact from exploitation
• Monitor affected devices for signs of compromise and be prepared to re-provision from secure baselines if tampering is detected
• Review and harden system initialization configurations to override insecure defaults where possible

# Example: Network isolation for Jetson devices pending patch
# Configure firewall rules to restrict access to Jetson device management interfaces
iptables -A INPUT -p tcp --dport 22 -s <trusted_management_subnet> -j ACCEPT
iptables -A INPUT -p tcp --dport 22 -j DROP

# Verify unique machine ID on each device
cat /etc/machine-id
# If duplicated across devices, regenerate with:
# systemd-machine-id-setup
