CVE-2026-92150— F´: GenericHub Malformed Buffer Assertion DoS

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 4.2.0 之前，Svc::GenericHub 模块中的 fromBufferDriver_handler 反序列化功能存在漏洞，原因是其接收处理程序使用 FW_ASSERT 对受外部影响的反序列化状态和类型进行验证，并允许命令有效载荷大小减法运算发生下溢。当未经认证的处理器间 Hub 对等节点发送截断的缓冲区、无效的 HubType 或仅含头部的命令调度有效载荷时，格式错误的 Hub 流量会导致进程中止或重启，从而引发拒绝服务

Vulnerability Title
F´: GenericHub Malformed Buffer Assertion DoS
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. Prior to 4.2.0, Svc::GenericHub fromBufferDriver_handler deserialization is vulnerable because the receive handler uses FW_ASSERT for externally influenced deserialization status and type validation and permits a command payload size subtraction to underflow. When an unauthenticated inter-processor hub peer sends a truncated buffer, an invalid HubType, or a header-only command-dispatch payload, malformed hub traffic aborts or resets the process, causing denial of service. This issue is fixed in version 4.2.0.
