CVE-2018-7480 on Ubuntu 18.04 LTS (bionic) - medium.
Description:
The blkcg_init_queue function in block/blk-cgroup.c in the Linux kernel before 4.11 allows local users to cause a denial of service (double free) or possibly have unspecified other impact by triggering a creation failure. It was discovered that a double free error existed in the block layer subsystem of the Linux kernel when setting up a request queue. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code.
