RETURN ADDRESS OVERFLOW BUFFER |
| 摘要 |
Embodiments of an invention for a return address overflow buffer are disclosed. In one embodiment, a processor includes a stack pointer to store a reference to a first return address stored on a stack, an obscured address stack pointer to store a reference to an encrypted second return address stored in a memory, hardware to decrypt the encrypted second return address to generate a decrypted second return address, and a return address verification logic, responsive to receiving a return instruction, to compare the first return address to the decrypted second return address. |

1. A processor, comprising:
a stack pointer to store a reference to a first return address stored on a stack; an internal return address buffer; a return address buffer pointer to store a reference to a second return address stored in the internal return address buffer; a return address verification logic, responsive to receiving a return instruction, to execute the return instruction using the second return address instead of the first return address. |
