Title:CVE-2018-20856 on Ubuntu 16.04 LTS (xenial) - medium.
Description:An issue was discovered in the Linux kernel before 4.18.7. In block/blk-core.c, there is an __blk_drain_queue() use-after-free because a certain error case is mishandled. It was discovered that a use-after-free error existed in the block layer subsystem of the Linux kernel when certain failure conditions occurred. A local attacker could possibly use this to cause a denial of service (system crash) or possibly execute arbitrary code.
