Abstract
In one example, a processor sends a memory access request including a data capability and a handle which references a master capability. In response to receiving the memory access request, a memory controller checks whether the handle references a valid master capability and checks whether the data capability is within a scope of the master capability. In response to determining that the master capability is valid and the data capability is within the scope of the master capability, the memory controller returns a result of the memory access request to the processor.
