CVE-2026-32705: Dronecode PX4 Drone Autopilot

Medium severity, CVSS 6.8. EPSS: 0.3% chance of exploitation in the next 30 days.

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.

Affected products

• Dronecode PX4 Drone Autopilot: before 1.17.0 (fixed in 1.17.0); version 1.17.0 only
