CVE-2026-32705: Dronecode px4 drone autopilot stack-based buffer overflow vulnerability

Dronecode · Px4 Drone Autopilot

PX4 autopilot is a flight control solution for drones. Prior to 1.17.0-rc2, the BST telemetry probe writes a string terminator using a device-provided length without bounds. A malicious BST device can report an oversized dev_name_len, causing a stack overflow in the driver and crashing the task (or enabling code execution). This vulnerability is fixed in 1.17.0-rc2.
