CVE-2017-5123

The waitid implementation in upstream kernels did not restrict the target destination to copy information results. This can allow local users to write to otherwise protected kernel memory, which can lead to privilege escalation.

This issue did not affect the versions of the Linux kernel as shipped with Red Hat Enterprise Linux as they did not include the upstream commit https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=4c48abe91be03d191d0c20cc755877da2cb35622 that introduced this issue.
