MAVLink task crash via unbounded filepath parsing
Published Dec 28, 2025 · Updated Dec 28, 2025
Stack-based buffer overflow in PX4 Autopilot 1.16.0 and earlier allows attackers to crash the MAVLink task via a crafted log path. MavlinkLogHandler parses a path token from logdata.txt into the 60-byte LogEntry.filepath stack buffer with an unbounded sscanf %s conversion. An attacker must create an overlong path through MAVLink FTP and then request the log list; exploitation interrupts telemetry and command handling.
