CVE-2017-5123

Priority
Description
As of commit 4c48abe91be0 ("waitid(): switch copyout of siginfo to
unsafe_put_user()") in v4.13, waitid() stopped performing access_ok()
checks on the infop argument, which allows for arbitrary kernel
memory writing.
Ubuntu-Description
Chris Salls discovered a missing access check in the waitid() system
call implementation in the Linux kernel. A local attacker could use
this to cause a denial of service (system crash) or possibly execute
arbitrary code.
