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. Join the discussion | GCVE Database | 08/28/2026, 09:31:49 UTC Added: 08/28/2026, 15:22:43 UTC |
