  3. CVE-2021-47037
In the Linux kernel, the following vulnerability has been resolved: ASoC: q6afe-clocks: fix reprobing of the driver Q6afe-clocks driver can get reprobed. For example if the APR services are restarted after the firmware crash. However currently Q6afe-clocks driver will oops because hw.init will get cleared during first _probe call. Rewrite the driver to fill the clock data at runtime rather than using big static array of clocks.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: ASoC: q6afe-clocks: corrección de reprobación del controlador El controlador Q6afe-clocks puede ser reprobado. Por ejemplo, si los servicios APR se reinician después de la falla del firmware. Sin embargo, actualmente el controlador Q6afe-clocks fallará porque hw.init se borrará durante la primera llamada a _probe. Vuelva a escribir el controlador para completar los datos del reloj en tiempo de ejecución en lugar de utilizar una gran variedad de relojes estáticos.
