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:
