Summary
tracing: Fix overflow in get_free_elt()
Details

In the Linux kernel, the following vulnerability has been resolved:

tracing: Fix overflow in getfreeelt()

"tracingmap->nextelt" in getfreeelt() is at risk of overflowing.

Once it overflows, new elements can still be inserted into the tracingmap even though the maximum number of elements (max_elts) has been reached. Continuing to insert elements after the overflow could result in the tracingmap containing "tracingmap->maxsize" elements, leaving no empty entries. If any attempt is made to insert an element into a full tracing_map using __tracing_map_insert(), it will cause an infinite loop with preemption disabled, leading to a CPU hang problem.

Fix this by preventing any further increments to "tracingmap->nextelt" once it reaches "tracingmap->maxelt".
