Impact
Remote, unauthenticated attackers can crash the application or achieve remote code execution via malformed packets. This requires network access to a system running F Prime's Svc::GenericHub.
Root cause
The Svc::GenericHub output-port dispatcher uses deserialized port indices without validating array bounds, causing an assertion failure or out-of-bounds heap memory access.
Affected systems
F Prime versions 4.1.0 up to (excluding) 4.2.0

Fix & remediation
Upgrade the F Prime framework dependency to version 4.2.0. If immediate patching is not possible, restrict network access to Svc::GenericHub ports or disable the hub component.
$ git checkout v4.2.0AI-suggested. Run it in staging first and check it against the vendor advisory. Why?
NVD description
F´ (F Prime) is a framework that enables development and deployment of spaceflight and other embedded software applications. From 4.1.0 until 4.2.0, Svc::GenericHub output-port dispatch is vulnerable because the deserialized port field is passed to serialOut_out, bufferOut_out, eventOut_out, or tlmOut_out without an explicit range check. When a remote hub packet supplies a port index outside the configured output-port array, assert-enabled builds abort, while builds without assertions can access an output-port array out of bounds, corrupt heap memory, and potentially allow remote code execution. This issue is fixed in version 4.2.0.
