of a variable stored on the stack, ultimately writing a controlled value
to the stack frame's stored return address. The most widely used defense
is the presence of a stack canary between the stack variables and the
-return address (``CONFIG_CC_STACKPROTECTOR``), which is verified just before
+return address (``CONFIG_STACKPROTECTOR``), which is verified just before
the function returns. Other defenses include things like shadow stacks.
