CVE-2026-53207

The CVE-2026-53207 issue affects the Linux kernel mm/memory-failure path, where concurrent MADV_HWPOISON calls on the same hugetlb page can deadlock the non-recursive hugetlb_lock. The root cause is a sequence where a GUP reference is dropped under the hugetlb_lock, allowing free_huge_folio to re...

kernel: Linux kernel: Denial of Service due to a deadlock in hugetlb folio migration

A flaw was found in the Linux kernel. A local attacker could exploit a deadlock vulnerability due to incorrect lock ordering between foliolock and immaprwsem when migrating hugetlb file-backed folios. This could lead to hung tasks and potential system-wide stalls, resulting in a Denial of Service...
