      "value": "OP-TEE Trusted OS is the secure side implementation of OP-TEE project, a Trusted Execution Environment. Versions prior to 3.19.0, contain an Improper Validation of Array Index vulnerability. The function `cleanup_shm_refs()` is called by both `entry_invoke_command()` and `entry_open_session()`. The commands `OPTEE_MSG_CMD_OPEN_SESSION` and `OPTEE_MSG_CMD_INVOKE_COMMAND` can be executed from the normal world via an OP-TEE SMC. This function is not validating the `num_params` argument, which is only limited to `OPTEE_MSG_MAX_NUM_PARAMS` (127) in the function `get_cmd_buffer()`. Therefore, an attacker in the normal world can craft an SMC call that will cause out-of-bounds reading in `cleanup_shm_refs` and potentially freeing of fake-objects in the function `mobj_put()`. A normal-world attacker with permission to execute SMC instructions may exploit this flaw. Maintainers believe this problem permits local privilege escalation from the normal world to the secure world. Version 3.19.0 contains a fix for this issue. There are no known workarounds."

      "value": "OP-TEE Trusted OS es la implementación segura del proyecto OP-TEE, un entorno de ejecución confiable. Las versiones anteriores a la 3.19.0 contienen una vulnerabilidad de validación incorrecta del índice de matriz. La función `cleanup_shm_refs()` es llamada tanto por `entry_invoke_command()` como por `entry_open_session()`. Los comandos `OPTEE_MSG_CMD_OPEN_SESSION` y `OPTEE_MSG_CMD_INVOKE_COMMAND` se pueden ejecutar desde el mundo normal a través de un OP-TEE SMC. Esta función no valida el argumento `num_params`, que solo se limita a `OPTEE_MSG_MAX_NUM_PARAMS` (127) en la función `get_cmd_buffer()`. Por lo tanto, un atacante en el mundo normal puede crear una llamada SMC que provocará una lectura fuera de los límites en `cleanup_shm_refs` y potencialmente la liberación de objetos falsos en la función `mobj_put()`. Un atacante normal con permiso para ejecutar instrucciones SMC puede aprovechar esta falla. Quienes lo mantienen creen que este problema permite una escalada de privilegios locales desde el mundo normal al mundo seguro. La versión 3.19.0 contiene una solución para este problema. No se conocen workarounds."
