In Eclipse ThreadX versions 6.0.1 through 6.5.2.202603, built with TX_ENABLE_EVENT_TRACE, the Module Manager lets a user-mode, memory-protected module register any function pointer as the kernel's trace-buffer-full callback, which the kernel calls from privileged code when the trace buffer wraps. A malicious module can thereby run its own code with kernel privilege, defeating module isolation, or fault the kernel with an invalid pointer.
