CVE-2026-53154

A flaw was found in the Linux kernel's huge page hugetlb memory management. When an error occurs during the copying of huge pages, the system fails to properly restore the memory reservation. This can lead to a leak of the virtual memory area VMA reservation. A local attacker could exploit this b...

CVE-2026-53207

The CVE describes a Linux kernel race in mm/memory-failure where two concurrent MADV_HWPOISON calls on the same hugetlb page can cause an AA deadlock in hugetlb_lock during get_huge_page_for_hwpoison. Root cause: a folio_put() path releases a GUP reference while hugetlb_lock is still held, and fr...
