Linux - mincore() Uninitialized Kernel Heap Page Disclosure Exploit

Linux mincore discloses uninitialized kernel heap pages. When walkpagerange is used on a VMHUGETLB VMA, callbacks from the mmwalk structure are only invoked for present pages. However, domincore assumes that it will always get callbacks for all pages in the range passed to walkpagerange, and when...
