Method and system for detection and neutralization of buffer overflow attacks

A system, comprising:

• a processor core coupled to a plurality of busses;
• an execution stack in a random access memory coupled to the plurality of busses;
• and
• a buffer overflow protection (BOP) logic coupled to the plurality of busses, the BOP logic receiving memory access requests from the plurality of busses,
• wherein the BOP logic is operable to detect a buffer overflow attack comprising a memory access request addressing the execution stack initiated by a program executing on the processor core.

A buffer overflow protection (BOP) apparatus, comprising:

• address range comparator logic coupled to a plurality of busses of a processor core to receive a memory access request from a program executing on the processor core;
• and
• violation generator logic coupled to the address comparator logic to receive a notification of a security violation,
• wherein the address comparator logic sends the notification to the violation generator logic if the memory access request comprises an instruction fetch request addressing an execution stack.
