## Overview

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

ASoC: codecs: rt1011: Use component to get the dapm context in spk_mode_put

The correct helper to use in rt1011_recv_spk_mode_put() to retrieve the
DAPM context is snd_soc_component_to_dapm(), from kcontrol we will
receive NULL pointer.

## Affected

- `Linux >= 5b35bb517f27fc2401ec3cfd8c02a127627a0188 < b10b2b15b45923ff2807eeb034d91a39b0a3e690`
- `Linux >= 5b35bb517f27fc2401ec3cfd8c02a127627a0188 < 30e4b2290cc2a8d1b9ddb9dcb9c981df1f2a7399`
- `Linux 6.19`
