kernel: mm/page_alloc: clear page->private in free_pages_prepare()
A flaw was found in the Linux kernel's memory management subsystem. When pages are freed, the page-private field is not properly cleared. If these pages are later reallocated as high-order pages and split, the tail pages can retain stale page-private values. This can lead to a use-after-free...
