CVE-2026-94023— Module delete dispatchers do not enforce kernel-object ownership before irreversible deletion

Quick assessment

Affected
Eclipse Foundation Eclipse ThreadX
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.

ThreadX 模块通过模块管理器（Module Manager）的分发层调用内核对象的删除服务。该分发层仅对指针提出一个问题：该对象是否位于模块自身的代码和数据之外。然而，这一策略仅适用于对象的使用场景；模块使用其并不拥有的对象是被支持且符合设计意图的—— 函数会根据名称搜索系统中已创建的对象，并返回由应用程序或其他模块创建的对象，从而允许模块向共享队列发送消息、获取共享信号量或取得共享互斥锁。 但销毁此类对象并不等同于共享它。任何模块只要拥有某个对象的指针，即可指定其名称，并通过具备特权的分发器将其删除。

Vulnerability Title
Module delete dispatchers do not enforce kernel-object ownership before irreversible deletion
Source: CVE Program / CVE List V5
Vulnerability Description
A ThreadX module reaches a kernel object's delete service through the Module Manager's dispatch layer, which asked one question about the pointer: does the object lie outside the module's own code and data. That is the policy for *using* an object, and using an object a module does not own is supported and intended — `txm_module_object_pointer_get_extended` searches the system's created objects by name and hands back objects the application created and objects other modules created, so that a module can send to a shared queue, take a shared semaphore or get a shared mutex. Destroying one of those is not sharing it. A module could name any object it had a pointer to and have the privileged dispatcher delete it.
