Descriptions

In Trusted Firmware-M through 1.3.0, cleaning up the memory allocated for a multi-part cryptographic operation (in the event of a failure) can prevent the abort() operation in the associated cryptographic library from freeing internal resources, causing a memory leak.

En Trusted Firmware-M hasta la versión 1.3.0, limpiar la memoria asignada para una operación criptográfica de varias partes (en caso de fallo) puede impedir que la operación abort() en la biblioteca criptográfica asociada libere recursos internos, causando un filtrado de la memoria
