_PAGE_HUGE 位而不是零值。对于无效的 pmd 条目应该也是如此因为 pmd_none() 由函数 free_pgd_range() 调用而 pmd_none() 由 huge_pte_clear() 返回 0。如此单一
_PAGE_HUGE 位也会被视为有效的 pte 表且会在 free_pmd_range() 中调用 free_pte_range()。 free_pmd_range() pmd = pmd_offset(pud, addr); do { next = pmd_addr_end(addr, end); if (pmd_none_or_clear_bad(pmd)) continue; free_pte_range(tlb, pmd, addr); } while (pmd++, addr = next, addr != end);此处的 invalid_pte_table 同时用于无效的大型 pte 条目和 pmd 条目。 (CVE-2024-56628)
