In the Linux kernel, the following vulnerability has been resolved: dmaengine: stm32: dmamux: fix device leak on route allocation Make sure to drop the reference taken when looking up the DMA mux platform device during route allocation. Note that holding a reference to a device does not prevent its driver data from going away so there is no point in keeping the reference.
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.
