CVE-2019-20811

CVE-2019-20811 affects the Linux kernel prior to 5.0.6, where a reference count is mishandled in rx_queue_add_kobject() and netdev_queue_add_kobject() within net/core/net-sysfs.c (CID-a3e23f719f5c). The issue was fixed in kernel 5.0.6 (ChangeLog-5.0.6). Exploitation would require local access and...
