CVE-2024-27022 (GCVE-0-2024-27022)

Vulnerability from cvelistv5 – Published: 2024-05-01 05:35 – Updated: 2026-08-05 11:29

Title

fork: defer linking file vma until vma is fully initialized

Summary

In the Linux kernel, the following vulnerability has been resolved: fork: defer linking file vma until vma is fully initialized Thorvald reported a WARNING [1]. And the root cause is below race: CPU 1 CPU 2 fork hugetlbfs_fallocate dup_mmap hugetlbfs_punch_hole i_mmap_lock_write(mapping); vma_interval_tree_insert_after -- Child vma is visible through i_mmap tree. i_mmap_unlock_write(mapping); hugetlb_dup_vma_private -- Clear vma_lock outside i_mmap_rwsem! i_mmap_lock_write(mapping); hugetlb_vmdelete_list vma_interval_tree_foreach hugetlb_vma_trylock_write -- Vma_lock is cleared. tmp->vm_ops->open -- Alloc new vma_lock outside i_mmap_rwsem! hugetlb_vma_unlock_write -- Vma_lock is assigned!!! i_mmap_unlock_write(mapping); hugetlb_dup_vma_private() and hugetlb_vm_op_open() are called outside i_mmap_rwsem lock while vma lock can be used in the same time. Fix this by deferring linking file vma until vma is fully initialized. Those vmas should be initialized first before they can be used.

There is no network or remote-peer input path into `dup_mmap()` or `hugetlbfs_punch_hole()`.\nAC:L - The attacker controls both sides of the race, looping `fork()` in one thread while another loops hole-punch/truncate on the same hugetlbfs fd, and the vulnerable window spans `hugetlb_dup_vma_private()` through `copy_page_range()` to `vm_ops-\u003eopen()`, which is widened to milliseconds simply by using a multi-GB mapping. No condition outside the attacker\u0027s influence is required.\nPR:L - Any unprivileged local user can reach this: `memfd_create(name, MFD_HUGETLB)` uses `HUGETLB_ANONHUGE_INODE`, which bypasses the `can_do_hugetlb_shm()`/`CAP_IPC_LOCK` check, and `MAP_NORESERVE` lets the mapping succeed even with no huge pages configured. No hugetlbfs mount, capability, or namespace privilege is needed.\nUI:N - The attacker\u0027s own process performs both the `fork()` and the `fallocate()`/`ftruncate()` that collide; no victim action, mount, or file open by another user is involved.\nS:U - The corruption is confined to kernel memory-management state (rwsem counters and hugetlb page tables) within the same kernel security authority, with no crossing of a VM, IOMMU, or sandbox boundary.\nC:H - Running `huge_pmd_unshare()` without the VMA lock reintroduces the shared-PMD page-table use-after-free that lock was added to prevent, letting a freed page-table page remain installed in another mm\u0027s PUD and be reallocated \u2014 yielding arbitrary physical memory read. Per kernel guidance, memory corruption of this class scores High.\nI:H - The same PMD page-table UAF gives an arbitrary-write primitive (attacker-controlled PTEs written into freed-and-reallocated memory map arbitrary physical frames), and the unbalanced `up_write()` underflows `sem-\u003ecount`, destroying mutual exclusion on the lock that guards hugetlb page-table teardown.\nA:H - The mismatched lock/unlock leaves the parent\u0027s `hugetlb_vma_lock-\u003erw_sema` permanently write-held, so every subsequent hugetlb fault, unmap, or `exit_mmap()` on that VMA blocks forever in D state \u2014 unkillable tasks and hung-task panic \u2014 in addition to the reported WARNING and UAF-induced oopses."

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
