It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-23097 in the wild and no public exploit code.\n\nAffected product: Linux kernel. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-23097/ (Markdown: https://insights.sbomify.com/CVE-2026-23097/index.md)","id":"CVE-2026-23097","markdown":"https://insights.sbomify.com/CVE-2026-23097/index.md","name":"CVE-2026-23097","record":{"aliases":["ALSA-2026:3463","ALSA-2026:3464","AZL-77181","BELL-CVE-2026-23097","DEBIAN-CVE-2026-23097","GHSA-3gqm-m375-7mp2","RHSA-2026:3463","RHSA-2026:3464","RLSA-2026:3463","RLSA-2026:3464","ROOT-OS-DEBIAN-11-CVE-2026-23097","ROOT-OS-DEBIAN-12-CVE-2026-23097","ROOT-OS-DEBIAN-13-CVE-2026-23097","ROOT-OS-UBUNTU-2204-CVE-2026-23097","ROOT-OS-UBUNTU-2404-CVE-2026-23097","UBUNTU-CVE-2026-23097"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel","requires_auth":"low_privilege","summary":"A lock ordering error in the Linux kernel's hugetlb migration path can cause a deadlock, leading to a denial of service.","user_interaction":"not_required","vuln_class":"race_condition"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":5.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-362","name":"Concurrent Execution using Shared Resource with Improper Synchronization"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nmigrate: correct lock ordering for hugetlb file folios\n\nSyzbot has found a deadlock (analyzed by Lance Yang):\n\n1) Task (5749): Holds folio_lock, then tries to acquire i_mmap_rwsem(read lock).\n2) Task (5754): Holds i_mmap_rwsem(write lock), then tries to acquire\nfolio_lock.\n\nmigrate_pages()\n  -\u003e migrate_hugetlbs()\n    -\u003e unmap_and_move_huge_page()     \u003c- Takes folio_lock!\n      -\u003e remove_migration_ptes()\n        -\u003e __rmap_walk_file()\n          -\u003e i_mmap_lock_read()       \u003c- Waits for i_mmap_rwsem(read lock)!\n\nhugetlbfs_fallocate()\n  -\u003e hugetlbfs_punch_hole()           \u003c- Takes i_mmap_rwsem(write lock)!\n    -\u003e hugetlbfs_zero_partial_page()\n     -\u003e filemap_lock_hugetlb_folio()\n      -\u003e filemap_lock_folio()\n        -\u003e __filemap_get_folio        \u003c- Waits for folio_lock!\n\nThe migration path is the one taking locks in the wrong order according to\nthe documentation at the top of mm/rmap.c.
