Description

PX4 autopilot is a flight control solution for drones. Prior to 1.17.0-rc2, the Zenoh uORB subscriber allocates a stack VLA directly from the incoming payload length without bounds. A remote Zenoh publisher can send an oversized fragmented message to force an unbounded stack allocation and copy, causing a stack overflow and crash of the Zenoh bridge task. This vulnerability is fixed in 1.17.0-rc2.
