Linux kernel built with Function Tracers(CONFIG_FUNCTION_TRACER) & Stack Tracers(CONFIG_STACK_TRACER) support is vulnerable to a NULL pointer deference flaw. It occurs while writing to `set_ftrace_pid' or `set_graph_function' files used by kernel tracers. A privileged(CAP_SYS_ADMIN) user could use this flaw to crash the system resulting in DoS.
