1) Privilege escalation (CVE-ID: CVE-2017-5123)

The vulnerability allows a local user to escalate privileges on the system.

The waitid implementation in kernel/exit.c in the Linux kernel through 4.13.4 does not check that the incoming argument points to the userspace. This can allow local users to write directly to kernel memory, which could lead to privilege escalation.
