Arnaud Lacombe f98ee76955 kconfig/nconf: prevent segfault on empty menu ... nconf does not check the validity of the current menu when help is requested (with either <F2>, '?' or 'h'). This leads to a NULL pointer dereference when an empty menu is encountered. The following reduced testcase exposes the problem: config DEP bool menu "FOO" config BAR bool "BAR" depends on DEP endmenu Issue will happen when entering menu "FOO" and requesting help. nconf is the only front-end which do not filter the validity of the current menu. Such filter can not really happen beforehand as other key which does not deals with the current menu might be entered by the user, so just bails out earlier if we encounter an invalid menu.
