Description		In the Linux kernel, the following vulnerability has been resolved: mm/damon/ops-common: ignore migration request to invalid nodes damon_migrate_pages() tries migration even if the target node is invalid. If users mistakenly make such invalid requests via DAMOS_MIGRATE_{HOT,COLD} action, the below kernel BUG can happen.
