CVE-2024-52319

Memory corruption or disclosure via unaligned huge-page clearing

Published Jan 11, 2025 · Updated Aug 5, 2026

Memory corruption in Linux kernel 6.11 through 6.12.6 allows local users to corrupt or disclose memory via an unaligned huge-page fault. hugetlb_no_page() passes the raw fault address to folio_zero_user(), which can forward it to clear_gigantic_page() without the huge-page alignment that routine requires. Exploitation requires local low-privilege access and a gigantic-page fault at an unaligned address; resulting damage is bounded to memory corruption or disclosure.
