CVE-2026-94192— Module object deallocation can free a live ThreadX kernel object

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 模块从模块管理器的对象池中为其内核对象分配控制块，并可以通过 接口按地址请求回收该内存。然而，模块管理器会无条件释放该内存，无论其中包含什么内容，包括内核仍在使用的控制块。需要注意的是，释放（deallocation）并不等同于删除（deletion）：对象仍保留在其类型对应的创建列表中；线程仍停留在就绪列表或挂起列表中的原有位置，并保持可调度状态；活动定时器也仍保留在定时器列表中。与此同时，字节池却可自由地将这些相同的字节重新分配给下一次分配请求。

Vulnerability Title
Module object deallocation can free a live ThreadX kernel object
Source: CVE Program / CVE List V5
Vulnerability Description
A ThreadX module allocates the control blocks of its kernel objects from the Module Manager's object pool, and can ask for that memory back by address with `txm_module_object_deallocate`. The manager released it whatever was in it, including a control block the kernel was still using. Deallocation is not deletion: the object stays on the created list for its type, a thread stays wherever it was on the ready or suspension lists and stays schedulable, and an active timer stays on the timer list. The byte pool is meanwhile free to hand those same bytes to the next allocation.
