  "details": "In the Linux kernel, the following vulnerability has been resolved:  ASoC: dapm: Fix off-by-one check on the second enum channel  The snd_soc_dapm_put_enum_double() rejects item[0] once it reaches e-\u003eitems, but it lets item[1] be equal to it.  Both go on to snd_soc_enum_item_to_val(), which indexes e-\u003evalues with no bound of its own, so an enum with a value table reads one element past the end.  The indexing arrived with the MUX consolidation, which relaxed the item[1] check in the same hunk.  The value MUX handler it deleted used \u003e= there, and the snd_soc_put_enum_double() in soc-ops.c still does.  Only adav80x pairs a value table with two shifts, and its second channel looks accidental, but the control does report two values. Writing three into it reads off the end of adav80x_mux_values.  The core catches that only under CONFIG_SND_CTL_INPUT_VALIDATION, which defaults off.",
