CVE-2026-86714 PX4 CVE debrief

Who should care

Defenders responsible for PX4 Autopilot systems should assess exposure and prioritize verification and updates. This vulnerability may impact systems using affected versions of PX4 Autopilot.

Why it matters

CVE-2026-86714 is a stack buffer over-read vulnerability in PX4 Autopilot's netman system command. Defenders should prioritize verifying and updating to a fixed version, reviewing system configurations, and monitoring for unusual activity. The vulnerability allows for potential exposure of stack memory and writing it into configuration files. Affected versions and specific impacts require verification from official sources.

• Potential exposure of stack memory
• Possible writing of stack memory into persistent network configuration files
• Need for verification of affected versions and system configurations
• Priority for updating to a fixed version of PX4 Autopilot

Technical summary

The netman system command in PX4 Autopilot through 1.17.0 is vulnerable to a stack buffer over-read. The command fails to validate the length of interface names supplied via the -i option, allowing for interface names of 74 bytes or more. This can cause the command to read beyond the buffer boundaries, potentially leaking stack memory to the console output or writing it into persistent network configuration files.

Defensive priority

Defenders should prioritize verifying and updating to a fixed version of PX4 Autopilot, reviewing system configurations for potential exposure, and monitoring for unusual activity.

Recommended defensive actions

• Verify and update to a fixed version of PX4 Autopilot
• Review system configurations for potential exposure
• Monitor for unusual activity
• Perform a thorough review of network configurations to identify potential vulnerabilities
• Check for any unauthorized access or modifications to system configurations
• Implement additional monitoring and logging to detect potential security incidents
• Review and update incident response plans to address potential security breaches

Evidence notes

The CVE record and NVD entry provide details on the vulnerability, including its description and potential impact. However, additional information on affected versions, exploitation, and remediation may require verification from official sources.
