In the Linux kernel, the following vulnerability has been resolved: mm,hugetlb: take hugetlb_lock before decrementing h->resv_huge_pages The h->*_huge_pages counters are protected by the hugetlb_lock, but alloc_huge_page has a corner case where it can decrement the counter outside of the lock. This could lead to a corrupted value of h->resv_huge_pages, which we have observed on our systems. Take the hugetlb_lock before decrementing h->resv_huge_pages to avoid a potential race.
