Abstract
An example processing system may comprise: a lower stack bound register configured to store a first memory address, the first memory address identifying a lower bound of a memory addressable via a stack segment; an upper stack bound register configured to store a second memory address, the second memory address identifying an upper bound of the memory addressable via the stack segment; and a stack bounds checking logic configured to detect unauthorized stack pivoting, by comparing a memory address being accessed via the stack segment with at least one of the first memory address and the second memory address.
