Date: October 14, 2025

In Eclipse ThreadX before version 6.4.3, the thread module has a setting of maximum priority. In some cases the check of that maximum priority wasn't performed, allowing, as a result, to obtain a thread with higher priority than expected and causing a possible denial of service.
