| 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.
