The madvise_willneed function in mm/madvise.c in the Linux kernel before 4.14.4 allows local users to cause a denial of service (infinite loop) by triggering use of MADVISE_WILLNEED for a DAX mapping.
The product contains an iteration or loop with an exit condition that cannot be reached, i.e., an infinite loop.
