CC3220SF: Possible memory leak in JSON library

6574982

Part Number: CC3220SF

Hello. There is probably a bug in the JSON library from TI SDK. See function <int16_t Json_createObject(Json_Handle *objHandle, Json_Handle templateHandle,
uint16_t maxObjectSize)>, file json.c. A user is not able to free memory in case __JSON_Init returns value different from JSON_RC__OK, because in this case the link to jsonObject is lost

Hello,

It looks like if the malloc is successful, the jsonObject handle is returned as objHandle, which can then be used in the application to call Json_destroyObject(). In this case, the application is responsible for freeing the object when it is done with it.

Best regards,

Sarah

But in case when rcode != JSON_RC__OK, objHandle pointer will not point to jsonObject array and memory leak will occur because user will not longer have an access to this array

Hello,

What version of the SDK are you looking at? In the latest CC32xx SDK 4.40, there is an else statement to free that jsonObject.

Best regards,
