A processor implementing techniques for processor extensions to protect stacks during ring transitions is provided. In one embodiment, the processor includes a plurality of registers and a processor core, operatively coupled to the plurality of registers. The plurality of registers is used to store data used in privilege level transitions. Each register of the plurality of registers is associated with a privilege level. An indicator to change a first privilege level of a currently active application to a second privilege level is received. In view of the second privilege level, a shadow stack pointer (SSP) stored in a register of the plurality of registers is selected. The register is associated with the second privilege level. By using the SSP, a shadow stack for use by the processor at the second privilege level is identified.

Abstract:
Methods and apparatuses relating to switching of a shadow stack pointer are described. In one embodiment, a hardware processor includes a hardware decode unit to decode an instruction, and a hardware execution unit to execute the instruction to: pop a token for a thread from a shadow stack, wherein the token includes a shadow stack pointer for the thread with at least one least significant bit (LSB) of the shadow stack pointer overwritten with a bit value of an operating mode of the hardware processor for the thread, remove the bit value in the at least one LSB from the token to generate the shadow stack pointer, and set a current shadow stack pointer to the shadow stack pointer from the token when the operating mode from the token matches a current operating mode of the hardware processor.
