CVE-2026-102710
Attacker model / Preconditions: a loaded `TXM_MODULE_USER_MODE | TXM_MODULE_MEMORY_PROTECTION`...
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.

Attacker model / Preconditions: a loaded `TXM_MODULE_USER_MODE | TXM_MODULE_MEMORY_PROTECTION`...
Attacker model / Preconditions: a loaded TXM_MODULE_USER_MODE | TXM_MODULE_MEMORY_PROTECTION module issuing kernel dispatch calls, on a build with TX_ENABLE_EVENT_TRACE.
A user-mode, memory-protected module can register an arbitrary function pointer as the global trace-full callback. The kernel calls it directly — no validation, no trampoline — from privileged kernel code when the trace buffer wraps.
An invalid pointer faults the kernel (DoS). A pointer into the module's own code was observed running with kernel privilege (CONTROL.nPRIV = 0), confirmed at runtime with a register capture inside that code.
