The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - arm64: mm: call pagetable dtor when freeing hot-removed page tables Since 5e8eb9aeeda3 (arm64: mm: always     call PTE/PMD ctor in __create_pgd_mapping()) page-table allocation on ARM64 always calls     pagetable_{pte,pmd,pud,p4d}_ctor(). This sets the page_type to PGTY_table, increments NR_PAGETABLE and     possible allocates a PTL. However the matching pagetable_dtor() calls were never added. With DEBUG_VM     enabled on kernel versions prior to v6.17 without 2dfcd1608f3a9 (mm/page_alloc: let page freeing clear     any set page type) this leads to the following warning when freeing these pages due to page->page_type     sharing page->_mapcount: BUG: Bad page state in process ... pfn:284fbb page: refcount:0 mapcount:0     mapping:0000000000000000 index:0x0 pfn:0x284fbb flags: 0x17fffc000000000(node=0|zone=2|lastcpupid=0x1ffff)     page_type: f2(table) page dumped because: nonzero mapcount Call trace: bad_page+0x13c/0x160

Fix this by calling pagetable_dtor() in     free_hotplug_pgtable_page() prior to freeing the page to undo the effects of calling pagetable_*_ctor().
