Both go on to\nsnd_soc_enum_item_to_val(), which indexes e->values with no bound of\nits own, so an enum with a value table reads one element past the end.\n\nThe indexing arrived with the MUX consolidation, which relaxed the\nitem[1] check in the same hunk.  The value MUX handler it deleted used\n>= there, and the snd_soc_put_enum_double() in soc-ops.c still does.\n\nOnly adav80x pairs a value table with two shifts, and its second\nchannel looks accidental, but the control does report two values.\nWriting three into it reads off the end of adav80x_mux_values.  The\ncore catches that only under CONFIG_SND_CTL_INPUT_VALIDATION, which\ndefaults off."
