Description (CNA)
Two issues in the ThreadX loadable-module loader, reached when a device loads an attacker-controlled module object via `_txm_module_manager_memory_load` / `_txm_module_manager_in_place_load` — APIs that take ONLY a base pointer, no image length, so every size/offset field in `TXM_MODULE_PREAMBLE` is fully attacker-trusted: (1) a heap OOB **read** (`code_size` trusted as the source-image length in the code-copy loop), and (2) a control-flow-integrity / defense-in-depth gap (module entry/start/callback/stop pointers computed as `code_start + preamble_offset` with only a `!= 0` check, and the preamble `checksum` never verified). No controlled OOB write was found (honest — the copy destination is overflow-guarded).
Affected (CNA)
| Vendor / product | Versions |
|---|---|
| Eclipse Foundation / `eclipse-threadx/threadx` (module manager / loadable-module loader) | affected current HEAD and prior (the `_txm_module_manager_*_load` APIs take no image length). |
