Local privilege escalation via inverted object validation

Privilege escalation in Eclipse ThreadX before 6.4.3 allows local users to read and write arbitrary memory through crafted syscalls. Object-use and object-creation macros in txm_module_manager_util.h use disjunctions that accept a pointer when the created-object check returns false, bypassing user-kernel isolation. Exploitation requires a low-privileged module and memory protection to be enabled; successful exploitation grants arbitrary access to vulnerable-system memory.
