      "value": "The Texas Instruments OMAP L138 (secure variants) trusted execution environment (TEE) performs an RSA check implemented in mask ROM when loading a module through the SK_LOAD routine. However, only the module header authenticity is validated. An adversary can re-use any correctly signed header and append a forged payload, to be encrypted using the CEK (obtainable through CVE-2022-25332) in order to obtain arbitrary code execution in secure context. This constitutes a full break of the TEE security architecture."

Sin embargo, s\u00f3lo se valida la autenticidad del encabezado del m\u00f3dulo. Un adversario puede reutilizar cualquier encabezado firmado correctamente y agregar un payload falsificado, que se cifrar\u00e1 mediante CEK (que se puede obtener a trav\u00e9s de CVE-2022-25332) para obtener la ejecuci\u00f3n de c\u00f3digo arbitrario en un contexto seguro. Esto constituye una ruptura total de la arquitectura de seguridad de TEE."
