CVE-2026-64295

The vulnerability CVE-2026-64295 affects the Linux kernel’s page_ext iteration API. The issue arises when memory hotplug advances the iterator past the last valid section, causing page_ext_lookup to dereference a NULL PFN. The root cause is that for_each_page_ext() can increment the iterator boun...
