Official description
Type confusion in the ASP could allow an attacker to pass a malformed argument to the Reliability, Availability, and Serviceability trusted application (RAS TA) potentially leading to a read or write to shared memory resulting in loss of confidentiality, integrity, or availability.

The underlying weakness: Access of Resource Using Incompatible Type
The product allocates or initializes a resource such as a pointer, object, or variable using one type, but it later accesses that resource using a type that is incompatible with the original type.
