CVE-2026-92156

6.5 medium SSVC exploitation: poc Deferred
NVD · CVE.org

F´ (F Prime) is a framework that enables development and deployment of spaceflight and other embedded software applications. Prior to 4.3.0, Svc::EventManager loqQueue_internalInterfaceHandler packetization is vulnerable because EventManager accepts up to the framework LogBuffer maximum, but packet descriptor, event identifier, and time-tag metadata consume part of the larger ComBuffer and leave a smaller remaining budget for log arguments; serialization failure then reaches an assertion. When a deployment bridges events through GenericHub into EventManager and forwards a legal Fw::LogBuffer larger than EventManager remaining log-argument budget, under standard F Prime assertion handling, a legal bridged event payload aborts or resets the process, causing denial of service. This issue is fixed in version 4.3.0.
