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.
The product calls free() twice on the same memory address, potentially leading to modification of unexpected memory locations.
