NVD Description

Note: Versions mentioned in the description apply only to the upstream dtrace-modules-3.8.13-118.18.2.el6uek package and not the dtrace-modules-3.8.13-118.18.2.el6uek package as distributed by Oracle. See How to fix? for Oracle:6 relevant fixed versions and status.

The do_shmat function in ipc/shm.c in the Linux kernel through 4.9.12 does not restrict the address calculated by a certain rounding operation, which allows local users to map page zero, and consequently bypass a protection mechanism that exists for the mmap system call, by making crafted shmget and shmat system calls in a privileged context.
