Descriptions
An issue was discovered in the Linux kernel before 5.0.1. There is a memory leak in register_queue_kobjects() in net/core/net-sysfs.c, which will cause denial of service.
Se descubrió un problema en el kernel de Linux versiones anteriores a 5.0.1. Se presenta una pérdida de memoria en la función register_queue_kobjects() en el archivo net/core/net-sysfs.c, lo que causará una denegación de servicio.
A flaw that allowed an attacker to leak kernel memory was found in the network subsystem where an attacker with permissions to create tun/tap devices can create a denial of service and panic the system.
