CVE-2017-16994

Priority
Medium
Description
The walk_hugetlb_range function in mm/pagewalk.c in the Linux kernel before
4.14.2 mishandles holes in hugetlb ranges, which allows local users to
obtain sensitive information from uninitialized kernel memory via crafted
use of the mincore() system call.
Ubuntu-Description
It was discovered that the HugeTLB component of the Linux kernel did not
properly handle holes in hugetlb ranges. A local attacker could use this to
expose sensitive information (kernel memory).
