Summary
F´ (F Prime) is a framework that enables development and deployment of spaceflight and other embedded software applications. Prior to 4.2.0, Svc::GenericHub fromBufferDriver_handler deserialization is vulnerable because the receive handler uses FW_ASSERT for externally influenced deserialization status and type validation and permits a command payload size subtraction to underflow. When an unauthenticated inter-processor hub peer sends a truncated buffer, an invalid HubType, or a header-only command-dispatch payload, malformed hub traffic aborts or resets the process, causing denial of service. This issue is fixed in version 4.2.0.
