Summary
  • (es) En el kernel de Linux, la siguiente vulnerabilidad ha sido resuelta: dmaengine: stm32: dmamux: corregir fuga de dispositivo en la asignación de ruta Asegúrese de liberar la referencia tomada al buscar el dispositivo de plataforma DMA mux durante la asignación de ruta. Tenga en cuenta que mantener una referencia a un dispositivo no evita que los datos de su controlador desaparezcan, por lo que no tiene sentido mantener la referencia.
