CVE-2026-92151 Details
Description
F´ (F Prime) is a framework that enables development and deployment of spaceflight and other embedded software applications. Prior to 4.2.0, Svc::Ccsds::SpacePacketDeframer dataIn_handler is vulnerable because the handler treats the minimum packet-length condition as FW_ASSERT rather than rejecting and returning the buffer. When a CCSDS telecommand frame leaves a payload of six bytes or fewer after TcDeframer removes its header and trailer, the assertion aborts or resets the flight-software process, causing denial of service. This issue is fixed in version 4.2.0.
A denial-of-service vulnerability has been identified in the NASA F' framework, specifically in the SpacePacketDeframer component of the CCSDS service. This issue affects versions prior to 4.2.0. The vulnerability arises because the dataIn_handler function improperly handles minimum packet length validation. Instead of rejecting packets that do not meet the length requirement, the function asserts the condition, which can crash or reset the flight software process. The problem occurs when a CCSDS telecommand frame, after removing its header and trailer, leaves a payload of six bytes or fewer. This vulnerability can disrupt command capabilities in space missions, requiring manual intervention to restore functionality.
Users can update to F' version 4.3, where this vulnerability has been fixed. Instructions for updating can be found in the F' release notes.
