"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nmm/memory-failure: fix hugetlb_lock AA deadlock in get_huge_page_for_hwpoison\n\nTwo concurrent madvise(MADV_HWPOISON) calls on the same hugetlb page can\ntrigger a recursive spinlock self-deadlock (AA deadlock) on hugetlb_lock\nwhen racing with a concurrent unmap:\n\n thread#0 thread#1\n -------- --------\n madvise(folio, MADV_HWPOISON)\n -> poisons the folio successfully\n madvise(folio, MADV_HWPOISON) unmap(folio)\n try_memory_failure_hugetlb\n get_huge_page_for_hwpoison\n spin_lock_irq(&hugetlb_lock) <- held\n __get_huge_page_for_hwpoison\n hugetlb_update_hwpoison()\n -> MF_HUGETLB_FOLIO_PRE_POISONED\n goto out:\n folio_put()\n refcount: 1 -> 0\n free_huge_folio()\n spin_lock_irqsave(&hugetlb_lock)\n -> AA DEADLOCK!\n\nThe out: path in __get_huge_page_for_hwpoison() calls folio_put() to drop\nthe GUP reference while the hugetlb_lock is still held by the hugetlb.c\nwrapper get_huge_page_for_hwpoison(). If concurrent unmap has released\nthe page table mapping reference, folio_put() drops the folio refcount to\nzero, triggering free_huge_folio() which attempts to re-acquire the\nnon-recursive hugetlb_lock.\n\nFix this by moving hugetlb_lock acquisition from the hugetlb.c wrapper\ninto get_huge_page_for_hwpoison(). Place spin_unlock_irq() before the\nfolio_put() at the out: label so the folio is always released outside the\nlock.\n\n[akpm@linux-foundation.org: fix race, rename label per Miaohe]"
