CVE-2026-94023

MediumCVSS 6.9/10Last modified Oct 20, 2026

Description

A ThreadX module reaches a kernel object's delete service through the Module Manager's dispatch layer, which asked one question about the pointer: does the object lie outside the module's own code and data. That is the policy for *using* an object, and using an object a module does not own is supported and intended — `txm_module_object_pointer_get_extended` searches the system's created objects by name and hands back objects the application created and objects other modules created, so that a module can send to a shared queue, take a shared semaphore or get a shared mutex.

Destroying one of those is not sharing it. A module could name any object it had a pointer to and have the privileged dispatcher delete it.
