"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nmm/hugetlb: restore reservation on error in hugetlb folio copy paths\n\nTwo sites in mm/hugetlb.c allocate a hugetlb folio via\nalloc_hugetlb_folio() (consuming a VMA reservation) and then call\ncopy_user_large_folio(), which became int-returning in commit 1cb9dc4b475c\n(\"mm: hwpoison: support recovery from HugePage copy-on-write faults\") and\ncan now fail (e.g. -EHWPOISON on a hwpoisoned source page). On the\nfailure path, folio_put() restores the global hugetlb pool count through\nfree_huge_folio(), but the per-VMA reservation map entry is left marked\nconsumed:\n\n - hugetlb_mfill_atomic_pte() resubmission path (UFFDIO_COPY)\n - copy_hugetlb_page_range() fork-time CoW path when\n hugetlb_try_dup_anon_rmap() fails (rare: pinned hugetlb anon\n folio under fork)\n\nUser-visible effect: on UFFDIO_COPY into a private hugetlb VMA where the\nresubmission copy fails, the reservation for that address is leaked from\nthe VMA's reserve map. A subsequent fault at the same address takes the\nno-reservation path, and under hugetlb pool pressure the task is SIGBUSed\nat an address it had previously reserved. The fork-time CoW path leaks\nthe same way in the child VMA's reserve map, though it requires the much\nrarer combination of pinned hugetlb anon page + hwpoisoned source.\n\nAdd the missing restore_reserve_on_error() call before folio_put() on both\nerror paths."
