Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: ASoC: rt711-sdca: se corrige la desreferencia del puntero NULL del kernel cuando se produce un error de E/S. La configuración inicial se escribirá antes de la función de sondeo del códec. Sin embargo, rt711->component aún no se ha asignado. Si se produce un error de E/S durante las operaciones de configuración inicial, provocará un pánico del kernel. Este parche cambió component->dev a slave->dev para solucionar este problema.
