A fix is available and has been applied in the Linux kernel source code as indicated by the listed commit hashes. Users and maintainers should update to the fixed kernel versions or apply the relevant patches to ensure the stream_config structure is properly initialized.
Description
A vulnerability in the Linux kernel's ASoC codec driver for rt712-sdca-dmic was fixed by zero-initializing the stream_config structure to prevent the type field from containing garbage values. This issue could lead to improper stream configuration due to uninitialized data being used.
