In some embodiments, a memory corruption prevention process includes detecting a memory instruction of a program, where the memory instruction specifies a virtual memory address of data. The memory corruption prevention process further includes accessing, in response to the memory instruction, a translation lookaside buffer (TLB) using at least a portion of the virtual memory address. The memory corruption prevention process further includes, in response to accessing the TLB, obtaining a physical memory address corresponding to the virtual memory address, where the physical memory address corresponds to the data. The memory corruption prevention process further includes, in response to accessing the TLB, obtaining an authentication value corresponding to the physical memory address. The memory corruption prevention process further includes determining, using the authentication value, whether the memory instruction is authorized to proceed.
