For the two-entry mux used by this driver, valid values are 0 and 1, so value 2 must be rejected as well. Accepting e->items can store an invalid mux state, pass it to the GPIO setter, and pass it on to the DAPM mux update path where it is used as an index into the enum text array. Use the same >= e->items check used by the ASoC enum helpers. A flaw was found in the Linux kernel's Advanced Linux Sound Architecture (ASoC) simple-mux audio codec. A local user or process with access to the ALSA sound control interface could exploit an incorrect bounds check in the…
