CVE-2026-102711
CVSS:4.0/AV:L/AC:H/AT:N/PR:N/UI:A/VC:H/VI:N/VA:L/SC:N/SI:N/SA:N
Summary
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 Software
| Vendor | Product | Version Range | Status |
|---|---|---|---|
| Eclipse Foundation | eclipse-threadx/threadx (module manager / loadable-module loader) | current HEAD and prior (the txm_module_manager*_load APIs take no image length). | affected |
