  "details": "In the Linux kernel, the following vulnerability has been resolved:  mm/memfd_luo: fix physical address conversion in put_folios cleanup  In memfd_luo_retrieve_folios()'s put_folios cleanup path:  1. kho_restore_folio() expects a phys_addr_t (physical address) but    receives a raw PFN (pfolio-\u003epfn). This causes kho_restore_page() to    check the wrong physical address (pfn \u003c\u003c PAGE_SHIFT instead of the    actual physical address).  2. This loop lacks the !pfolio-\u003epfn check that exists in the main    retrieval loop and memfd_luo_discard_folios(), which could    incorrectly process sparse file holes where pfn=0.  Fix by converting PFN to physical address with PFN_PHYS() and adding the !pfolio-\u003epfn check, matching the pattern used elsewhere in this file.
