Description (CNA)
In the Linux kernel, the following vulnerability has been resolved: ASoC: SDCA: Validate written enum value in ge_put_enum_double() ge_put_enum_double() passes the user-supplied enumeration index item[0] to snd_soc_enum_item_to_val() without checking it against the number of items in the enum: ret = snd_soc_enum_item_to_val(e, item[0]); snd_soc_enum_item_to_val() indexes the heap-allocated e->values[] array with that index (e->values is set from a devm_kcalloc() of e->items entries), so a control write with an out-of-range item[0] reads past the end of the values buffer. The bounds check in snd_soc_dapm_put_enum_double() only runs afterwards, so it does not prevent the read here. Reject an out-of-range item before using it, matching the other enum put handlers. This issue was pointed out by the Sashiko AI review bot while reviewing a related enum-validation series: https://lore.kernel.org/all/20260609125735.CEB651F00893@smtp.kernel.org/
