CVE-2026-64243

In the Linux kernel, the following vulnerability has been resolved:

ASoC: codecs: simple-mux: Fix enum control bounds check

simple_mux_control_put() rejects values greater than e->items, but

enum control values are zero based. 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.
