Official description
In the Linux kernel, the following vulnerability has been resolved: mm/huge_memory: preserve pmd_swp_uffd_wp on device-private PMD downgrade change_non_present_huge_pmd() rewrites a writable device-private PMD swap entry into a readable one without carrying pmd_swp_uffd_wp() across. The PTE-level change_softleaf_pte() does this correctly; mirror that here, matching what copy_huge_pmd() does for the fork path. Without the carry, a plain mprotect() over a UFFD_WP-marked device-private THP strips the bit and the trap is bypassed on swap-in.
