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

mm/vmscan: fix a bug calling wakeup_kswapd() with a wrong zone index

With numa balancing on, when a numa system is running where a numa node doesn't have its local memory so it has no managed zones, the following oops has been observed. It's because wakeup_kswapd() is called with a wrong zone index, -1. Fixed it by checking the index before calling wakeup_kswapd().
