CVE-2019-20811 [MEDIUM] CWE-460 kernel: net-sysfs: *_queue_add_kobject refcount issue
kernel: net-sysfs: *_queue_add_kobject refcount issue
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.
A flaw was found in the way the rx_queue_add_kobject and netdev_queue_add_kobject functions in the Linux kernel handled refcounting of certain objects. This flaw allows a local user who can trigger the error code path to use this vulnerability to disturb the integrity of the system.
Statement: This issue is rated as having Low impact because of the preconditions needed to trigger the error code path (privileges).
Mitigation: Mitigation for this issue is either not available or the currently available options don't meet the Red Hat Product Se
