Abstract: Systems and methods for validating virtual address translation. An example processing system comprises: a processing core to execute a first application associated with a first privilege level and a second application associated with a second privilege level, wherein a first set of privileges associated with the first privilege level includes a second set of privileges associated with the second privilege level; and an address validation component to validate, in view of an address translation data structure maintained by the first application, a mapping of a first address defined in a first address space of the second application to a second address defined in a second address space of the second application.
