A stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function).

CWE-787 Out-of-bounds Write

The product writes data past the end, or before the beginning, of the intended buffer.
