The _XkbSetCompatMap() function attempts to resize the `sym_interpret`
buffer.
However, It didn't update its size properly. It updated `num_si` only,
without updating `size_si`.
This may lead to local privilege escalation if the server is run as root
or remote code execution (e.g. x11 over ssh).

X Server
The X server accepts requests from client applications to create windows, which are (normally rectangular) "virtual screens" that the client program can draw into.
Windows are then composed on the actual screen by the X server (or by a separate composite manager) as directed by the window manager, which usually communicates with the user via graphical controls such as buttons and draggable titlebars and borders.
