CVE-2025-68292

The CVE-2025-68292 issue concerns the Linux kernel memfd hugetlb folio allocation. A path used by memfd bypassed the normal page fault handler (hugetlb_no_page), omitting three initialisation steps that could leak kernel memory or cause races: (1) folios not zeroed, risking information disclosure...
