## Overview

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.

## Affected

- `eclipse_threadx >= 6.0.1 <= 6.5.2.202603`

## Remediation

Refer to the linked advisories for vendor-supplied fixes and affected version ranges.
