It also allows to show the contents of registers using the :registers or :display ex command. When redirecting the output of :display to a register, Vim will free the register content before storing the new content in the register. Now when redirecting the :display command to a register that is being displayed, Vim will free the content while shortly afterwards trying to access it, which leads to a use-after-free. Vim pre 9.1.1115 checks in the ex_display() function, that it does not try to redirect to a register while displaying this register at the same time. However this check is not complete, and so Vim does not check the + and * registers (which typically donate the X11/clipboard registers, and when a clipboard connection is not possible will fall back to use register 0 instead.
