Abstract: In one example in accordance with the present disclosure, enforcement of memory reference object loading indirection is described. According to a method, at a register, it is determined from an indirection counter of a first memory referencing object (MRO) in one of a number of registers of a processor of the computing device, whether a second MRO is loadable. When the indirection counter of the first MRO indicates a second MRO is loadable, the second MRO is loaded from the memory device to one of the number of registers. The second MRO also includes an indirection counter. The indirection counter of the loaded second MRO is changed, at the register that contains it, based on the indirection counter of the first MRO to enforce a degree of MRO loading indirection. Further, MRO loading is prohibited when an indirection counter reaches zero by invalidating a capability counter of a subsequent MRO at the register.
