Summary

Eclipse ThreadX from 6.0.1 through 6.5.1.202602a is affected. The module object deallocation function releases memory that still holds a kernel object control block the kernel is using (CWE-416). A local user with low privileges can affect confidentiality, integrity and availability, because the freed bytes can be reallocated to another use.

Description from the CNA

A ThreadX module allocates the control blocks of its kernel objects from the Module Manager's object pool, and can ask for that memory back by address with `txm_module_object_deallocate`. The manager released it whatever was in it, including a control block the kernel was still using. Deallocation is not deletion: the object stays on the created list for its type, a thread stays wherever it was on the ready or suspension lists and stays schedulable, and an active timer stays on the timer list. The byte pool is meanwhile free to hand those same bytes to the next allocation.
