Details

PX4 Autopilot through 1.17.0 contains a null pointer dereference vulnerability in param_set_default_file() and param_set_backup_file() functions that allows attackers to crash the autopilot process. Attackers can invoke 'param select' or 'param select-backup' commands with no path argument from any PX4 shell to trigger the crash.

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.
