CVE-2026-102711
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).
CVSS
- Versión: 4.0
- Vector: 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/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X
- Puntuación base: 5.7
Probabilidad de explotación (EPSS)
- Probabilidad de explotación en los próximos 30 días: 0.07%
- Percentil entre todas las CVEs puntuadas: 0
- Fecha de la puntuación: 4/10/2026
EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).
🎯 Técnicas ATT&CK
Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.
- Explotación
T1203Exploitation for Client Executionexecution85 % - Impacto principal
T1005Data from Local Systemcollection80 % - Impacto secundario
T1059Command and Scripting Interpreterexecution70 %
AV:L sin privilegios pero con UI:A (interacción del usuario para cargar módulo malicioso) indica escalada local. OOB read accede a memoria del proceso; debilidad de integridad en punteros de control de flujo permite ejecución de código del atacante.
Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.
