In versions 5.5.4 and 6.0, several ESP-TEE secure-service wrappers in esp_secure_services.c and esp_secure_services_iram.c validated only some of the caller-supplied pointer arguments, leaving input pointer arguments unchecked. Because the underlying TEE-protected hardware peripherals (e.g., ECC, SHA, SPI) run in RISC-V machine mode (M-mode) with full address-space access, a caller could supply pointers into TEE-exclusive memory as inputs, causing the peripheral to read TEE memory and return results derived from it to the REE. Depending on the wrapper, the result contains raw bytes from TEE memory, a computed function of TEE memory recoverable through repeated calls, or a single bit per call that forms an oracle for incremental disclosure of TEE-resident sensitive data. This issue has been patched in versions 5.5.5 and 6.0.1."}, {"lang": "es", "value": "ESF-IDF es el Framework de Desarrollo de Internet de las Cosas (IoT) de Espressif.

Debido a que los perif\u00e9ricos de hardware subyacentes protegidos por TEE (por ejemplo, ECC, SHA, SPI) se ejecutan en modo m\u00e1quina RISC-V (modo M) con acceso completo al espacio de direcciones, un llamador podr\u00eda proporcionar punteros a memoria exclusiva de TEE como entradas, haciendo que el perif\u00e9rico lea la memoria TEE y devuelva resultados derivados de ella al REE.
