CVE-2026-118052— Module Manager loaders leave the manager mutex held when a module preamble's sizes overflow, blocking every later module operation

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.

在 Eclipse ThreadX 6.0.1 至 6.5.2.202603 版本中，当模块前导声明（module preamble）中指定的数据区或栈区大小导致分配运算发生溢出时，模块管理器（Module Manager）的加载器会返回溢出错误，但不会释放模块管理器的互斥锁（mutex）。加载此类镜像会导致后续所有线程中的模块加载、启动、停止和卸载操作被阻塞，直至系统重置。

Vulnerability Title
Module Manager loaders leave the manager mutex held when a module preamble's sizes overflow, blocking every later module operation
Source: CVE Program / CVE List V5
Vulnerability Description
In Eclipse ThreadX versions 6.0.1 through 6.5.2.202603, the Module Manager loaders return an overflow error without releasing the Module Manager mutex when a module preamble declares a data or stack size that overflows the allocation arithmetic. Loading such an image blocks every later module load, start, stop and unload from other threads until the system is reset.
