Vulnerability from github – Published: 2026-09-29 18:32 – Updated: 2026-09-29 18:32

Details

PX4 Autopilot through 1.17.0 contains a NULL pointer dereference vulnerability in the sd_stress command where the -b byte count parameter is parsed without validation before being passed to malloc() and memset(). Attackers with shell access, including through MAVLink, can supply invalid byte count values to crash the flight controller.

Severity

6.5 (Medium)


                  
                    CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
