- mm/vmscan: fix a bug calling wakeup_kswapd() with a wrong zone index
- Details
-
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 wakeupkswapd() is called with a wrong zone index, -1. Fixed it by checking the index before calling wakeupkswapd().
BUG: unable to handle page fault for address: 00000000000033f3
PF: supervisor read access in kernel mode
PF: error_code(0x0000) - not-present page
