Name of the Vulnerable Software and Affected Versions PX4 autopilot versions prior to 1.17.0-rc2

Description PX4 autopilot is a flight control solution for drones. The Zenoh uORB subscriber allocates a stack-based Variable Length Array (VLA) directly from the incoming payload length without any limitations. A remote Zenoh publisher can exploit this by sending an oversized fragmented message, which forces an unbounded stack allocation and copy operation. This can lead to a stack overflow and subsequent crash of the Zenoh bridge task.

Recommendations Update to version 1.17.0-rc2 or later.
