CVE-2026-32705

Summary: The CVE affects the PX4 autopilot BST telemetry driver. Before version 1.17.0-rc2, the BST device can report an oversized dev_name_len, and the driver writes a string terminator without bounds, causing a stack overflow that can crash the task or enable code execution. Root cause: device-...

CVE-2026-32705 PX4 autopilot BST Device Name Length Can Overflow Driver Buffer

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 devnamelen, causing a stack overflow in the driver and crashing the task or...
