Subject: CVE request - Linux kernel: tracing NULL pointer dereference

   Hi,

Linux kernels built with Function Tracers and Stack Trackers are vulnerable to 
a NULL pointer dereference flaw. It occurs while writing to `set_ftrace_pid' 
and `set_graph_function' files used by the kernel tracers.

A privileged user/program could use this flaw to crash the kernel, resulting 
in DoS.

Upstream fix:
-------------
  -> https://git.kernel.org/linus/6a76f8c0ab19f215af2a3442870eeb5f0e81998d

Reference:
----------
  -> https://bugzilla.redhat.com/show_bug.cgi?id=952197

Thank you.
