Subject: Information Leak in mincore() in the Linux Kernel CVE-2017-16994


Mitre has allocated CVE-2017-16994 for this bug found by Google P0 team member jannh.

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.


Ciao, Marcus
