Descriptions

Memory leak in the irda_bind function in net/irda/af_irda.c and later in drivers/staging/irda/net/af_irda.c in the Linux kernel before 4.17 allows local users to cause a denial of service (memory consumption) by repeatedly binding an AF_IRDA socket.

Fuga de memoria en la función irda_bind en net/irda/af_irda.c y siguientes en drivers/staging/irda/net/af_irda.c en el kernel de Linux en versiones anteriores a la 4.17 permite que usuarios locales provoquen una denegación de servicio (consumo de memoria) enlazando repetidamente un socket AF_IRDA.
