CVE-2026-92152— F´: Unvalidated Port Index in GenericHub

Quick assessment

Affected
nasa fprime
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

F´（F Prime）是一个用于开发和部署航天飞行及其他嵌入式软件应用的框架。在版本 4.1.0 到 4.2.0 之间，Svc::GenericHub 的输出端口分发机制存在安全漏洞，因为反序列化后的端口字段在未进行显式范围检查的情况下被直接传递给了 serialOut_out、bufferOut_out、eventOut_out 或 tlmOut_out 等函数。当远程中心节点数据包提供超出配置的输出端口数组索引时，启用断言（assertion）的构建版本会中止程序执行；而未启用断言的构建版本则可能访问输出端口数

Vulnerability Title
F´: Unvalidated Port Index in GenericHub
Source: CVE Program / CVE List V5
Vulnerability 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.
