Short explanation
The CVE-2026-92151 vulnerability in the F´ (F Prime) framework stems from the Svc::Ccsds::SpacePacketDeframer component treating the minimum packet-length condition as an assertion instead of rejecting the buffer. CCSDS telecommand frames leaving a payload of six bytes or fewer cause the flight-software process to abort or reset, resulting in denial of service.
This security flaw can cause flight-software processes used in spaceflight and embedded software applications to crash or reset, leading to a denial of service [S0].
What should be done?
- Update to version 4.2.0 or later
- Follow vendor advisories
- Apply relevant patches and security announcements
Chain of evidence and sources
CVE-2026-92151 zafiyeti, 4.2.0 öncesi F´ sürümlerindeki Svc::Ccsds::SpacePacketDeframer bileşenini etkiler.
Altı bayt veya daha kısa yük bırakan CCSDS komut çerçeveleri hizmet engellemeye neden olur.
Bu sorun sürüm 4.2.0 ile giderilmiştir.
Show the technical text from the sources
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.
