A flaw was found in the hugetlb_mcopy_atomic_pte function in mm/hugetlb.c in the Linux kernel before 4.13. A superfluous implicit page unlock for VM_SHARED hugetlbfs mapping could trigger a local denial of service (BUG).
A flaw was found in the Linux kernel when freeing pages in hugetlbfs. This could trigger a local denial of service by crashing the kernel.
