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.
