Is buffer overflow the only possible bug associated with program stack?

Is buffer overflow the only possible bug associated with C/C++ program stack? are there any other bugs which can happen at program stack in a single/multi threaded C/C++ program.

I was reading this paper (Learning from Mistakes — A Comprehensive Study on Real World Concurrency Bug Characteristics) on concurrency bugs, and started thinking that such concurrency bugs do not happen at stack as it is private to threads.

Thanks
