A flaw was found in the way perf_trace_event_perm() function in the Linux kernel checked permissions for function tracer functionality, allowing unprivileged local user to enable function tracing.
As a result, unprivileged local user could make the system unusable (DoS).
This issue does not affect the version of the kernel package as shipped with Red Hat Enterprise Linux 5 and 6.
Patch(es) available on kernel-3.10.0-58.el7
