# Eclipse ThreadX: loaded modules can control other modules' threads

In Eclipse ThreadX 6.0.1 through 6.5.2.202603, the Module Manager's thread-control services do not check that a thread belongs to the calling module. Any loaded module can suspend, resume, terminate, reset or re-prioritise other threads, causing denial of service or changing scheduling.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check the ThreadX version in use against `6.0.1` through `6.5.2.202603`
- Look for the Module Manager (user-mode, memory-protected modules) in the build configuration

## From the sources

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.
