Descriptions

In the Linux kernel before 5.0.3, a memory leak exits in hsr_dev_finalize() in net/hsr/hsr_device.c if hsr_add_port fails to add a port, which may cause denial of service, aka CID-6caabe7f197d.

En el kernel de Linux versiones anterior a 5.0.3, se presenta una pérdida de memoria en la función hsr_dev_finalize() en el archivo net/hsr/hsr_device.c si hsr_add_port no puede agregar un puerto, lo que puede causar una denegación de servicio, también se conoce como CID-6caabe7f197d.
