    摘要: In one embodiment, a processor comprises: a first register to store a first bound value for a stack to be stored in a memory; a second register to store a second bound value for the stack; a checker logic to determine, prior to an exit point at a conclusion of a function to be executed on the processor, whether a value of a stack pointer is within a range between the first bound value and the second bound value; and a logic to prevent a return to a caller of the function if the stack pointer value is not within the range. Other embodiments are described and claimed.

    摘要: Systems and techniques for preventing malicious instruction execution are described herein. A first instance of an instruction for a graphics processing unit (GPU) may be received. The instruction may be placed in a target list. A notification that the instruction caused a problem with the GPU may be received. The instruction may be moved from the target list to a black list in response to the notification. A second instance of the instruction may be received. The second instance of the instruction may be prevented from executing on the GPU in response to the instruction being on the black list.
