In the Linux kernel, the following vulnerability has been resolved:
mm: swap: fix potential buffer overflow in setup_clusters()
In setup_swap_map(), we only ensure badpages are in range (0, last_page].
As maxpages might be < last_page, setup_clusters() will encounter a buffer
overflow when a badpage is >= maxpages.
Only call inc_cluster_info_page() for badpage which is < maxpages to fix
the issue.
