CVE-2019-20811

Priority
Description
An issue was discovered in the Linux kernel before 5.0.6. In
rx_queue_add_kobject() and netdev_queue_add_kobject() in
net/core/net-sysfs.c, a reference count is mishandled, aka
CID-a3e23f719f5c.
Ubuntu-Description
Yue Haibing discovered that the Linux kernel did not properly handle
reference counting in sysfs for network devices in some situations. A local
attacker could possibly use this to cause a denial of service.
