Vulnerability Details : CVE-2021-32032
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.
