Summary
In the Linux kernel, the following vulnerability has been resolved:
ASoC: codecs: hdac_hdmi: Validate written enum value
hdac_hdmi_set_pin_port_mux() uses the written enum value to index the texts array before calling snd_soc_dapm_put_enum_double(), which validates that the value is within the enum item range.
An out-of-range value can therefore make the driver read past the texts array before the helper rejects the write. Move the lookup after the helper has accepted the value.
