Description Adam Mariš 2017-04-10 16:11:19 UTC

The Linux kernel package 3.16.0-28 on Ubuntu 14.04 LTS mishandles a series of mmap system calls for /dev/zero with different starting addresses, with a stated impact of "allowing for a local user to possibly gain root access," aka an "inode integer overflow."
