MEDIUM 5.5EPSS 0.38%
Does this matter?
Lower severity and a low EPSS score (0.38%). Track it; it rarely justifies an emergency change on its own.
Description
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).
