In the Linux kernel, the following vulnerability has been resolved:
rcu-tasks: Fix showrcutaskstracegp_kthread buffer overflow
There is a possibility of buffer overflow in showrcutaskstracegp_kthread() if counters, passed to sprintf() are huge. Counter numbers, needed for this are unrealistically high, but buffer overflow is still possible.
Use snprintf() with buffer size instead of sprintf().
