CVE-2026-115654— User-mode module can suspend, terminate, re-prioritise and abort the waits of threads it does not own

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，模块管理器（Module Manager）的线程控制服务未验证用户态、内存保护模块所传入的线程是否确实属于该模块。因此，任何已加载的模块均可挂起、恢复、终止、重置或重新调整应用线程及其他模块线程的优先级，并中断其等待操作，从而导致服务拒绝（DoS）或改变系统的调度行为。

User-mode module can suspend, terminate, re-prioritise and abort the waits of threads it does not own
Source: CVE Program / CVE List V5
Vulnerability Description
In Eclipse ThreadX versions 6.0.1 through 6.5.2.202603, the Module Manager's thread-control services do not check that a thread passed by a user-mode, memory-protected module belongs to that module. Any loaded module can suspend, resume, terminate, reset or re-prioritise application threads and other modules' threads and abort their waits, denying service or changing how the system schedules them.
