Lifecycle Timeline
3Description
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.
Analysis
PX4 autopilot versions prior to 1.17.0-rc2 contain a stack overflow vulnerability in the BST telemetry probe driver that allows a malicious BST device to trigger a buffer overflow by reporting an oversized dev_name_len parameter without bounds checking. An attacker with physical access to inject a malicious BST device can crash the autopilot task or potentially achieve arbitrary code execution, impacting drone flight safety and control systems. …
