CVE-2024-38951

Service crash via oversized MAVLink valid_points field

Published Jun 25, 2024 · Updated Oct 28, 2024

Buffer overflow in PX4-Autopilot 1.12.3 allows remote attackers to crash the autopilot via a crafted MAVLink message. The MAVLink module processes a valid_points field greater than five without enforcing the expected bound, causing a heap overflow. Reachability requires access to a MAVLink link; the demonstrated consequence is termination of the software-in-the-loop simulation.
