Abstract

Methods, systems, and computer readable media for preventing code reuse attacks are disclosed. According to one method, the method includes executing, on a processor, code in a memory page related to an application, wherein the memory page is protected. The method also includes detecting a read request associated with the code. The method further includes after detecting the read request, modifying, without using a hypervisor, at least one memory permission associated with the memory page such that the code is no longer executable after the code is read.
