A method for validation of virtual function pointers includes compiling a source code file with one or more classes whereby each of the classes has a virtual table, and the compiling includes associating a security check function with the virtual function invocation site such that the associated security check function is executed prior to an invocation of the virtual function, generating a class hierarchy hash table (CHHT), whereby when the compiled source code file is executed, the security check function is used to determine whether an invoked virtual function pointer of a virtual function associated with the security check function is valid by looking up an indicator in the CHHT according to a hash result of the virtual function pointer and an address of a virtual table containing the virtual function pointer.
