In the Linux kernel before 4.20.2, kernel/sched/fair.c mishandles leaf cfs_rqs, which allows attackers to cause a denial of service (infinite loop in update_blocked_averages) or possibly have unspecified other impact by inducing a high load.
The product contains an iteration or loop with an exit condition that cannot be reached, i.e., an infinite loop.
