In migrate_vma_collect_pmd(), these functions may be invoked on non-present entries (e.g., device-private entries), leading to potential crashes from pte_pfn() or incorrect dirty folio accounting from pte_dirty(). Fix both by guarding with pte_present() checks.</p> <p><strong>Affected:</strong> Linux</p> <p>In the Linux kernel, the following vulnerability has been resolved:</p> <p>mm: migrate_device: fix pte_pfn/pte_dirty called on non-present PTE</p> <p>pte_pfn() and pte_dirty() have undefined behaviour when called on a non-present PTE.
