Summary
mm/compaction: handle free_pages_prepare() properly in compaction_free()
Details

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

mm/compaction: handle free_pages_prepare() properly in compaction_free()

free_pages_prepare() can fail but compaction_free() does not handle the failure case. Failed pages should not be added back to cc->freepages for future use, since they can be either PageHWPoison or free_page_is_bad() and might cause data corruption.
