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-2025-37984 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-2025-37984/ (Markdown: https://insights.sbomify.com/CVE-2025-37984/index.md)","id":"CVE-2025-37984","markdown":"https://insights.sbomify.com/CVE-2025-37984/index.md","name":"CVE-2025-37984","record":{"aliases":["BELL-CVE-2025-37984","DEBIAN-CVE-2025-37984","GHSA-p8pc-4q8f-r225","ROOT-OS-DEBIAN-12-CVE-2025-37984","ROOT-OS-UBUNTU-2204-CVE-2025-37984","ROOT-OS-UBUNTU-2404-CVE-2025-37984","UBUNTU-CVE-2025-37984"],"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":"An integer overflow in the Linux kernel's ECDSA crypto module can cause a denial of service when processing large key sizes.","user_interaction":"not_required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":7,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-190","name":"Integer Overflow or Wraparound"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\ncrypto: ecdsa - Harden against integer overflows in DIV_ROUND_UP()\n\nHerbert notes that DIV_ROUND_UP() may overflow unnecessarily if an ecdsa\nimplementation's -\u003ekey_size() callback returns an unusually large value.\nHerbert instead suggests (for a division by 8):\n\n  X / 8 + !!(X \u0026 7)\n\nBased on this formula, introduce a generic DIV_ROUND_UP_POW2() macro and\nuse it in lieu of DIV_ROUND_UP() for -\u003ekey_size() return values.\n\nAdditionally, use the macro in ecc_digits_from_bytes(), whose \"nbytes\"\nparameter is a -\u003ekey_size() return value in some instances, or a\nuser-specified ASN.1 length in the case of ecdsa_get_signature_rs().","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"crypto: ecdsa - Harden against integer overflows in DIV_ROUND_UP()","id":"CVE-2025-37984","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"linux:linux_kernel","products":["linux:linux_kernel"],"type":"integer_overflow","year":"2025"},"n_packages":0,"n_references":4,"next":{"headline":"USB: wdm: close race between wdm_open and wdm_wwan_port_stop","id":"CVE-2025-37985"},"packages":[],"prev":{"headline":"qibfs: fix _another_ leak","id":"CVE-2025-37983"},"products":["Linux"],"published":"2025-05-20","related":[{"cvss_score":8.8,"headline":"Linux Kernel Out-of-Bounds Write","id":"CVE-2026-53266","kev_date_added":"2026-09-18","published":"2026-06-25"},{"cvss_score":8.8,"headline":"Linux Kernel Improper Input Validation","id":"CVE-2013-6282","kev_date_added":"2022-09-15","published":"2013-11-19"},{"cvss_score":8.4,"headline":"Linux Kernel Heap-Based Buffer Overflow","id":"CVE-2022-0185","kev_date_added":"2024-08-21","published":"2022-02-11"},{"cvss_score":8.4,"headline":"Linux Kernel Privilege Escalation","id":"CVE-2013-2094","kev_date_added":"2022-09-15","published":"2013-05-14"},{"cvss_score":7.8,"headline":"Linux Kernel Unspecified","id":"CVE-2026-53362","kev_date_added":"2026-08-27","published":"2026-07-04"},{"cvss_score":7.8,"headline":"Linux Kernel Missing Initialization of a Variable","id":"CVE-2026-46300","kev_date_added":"2026-10-28","published":"2026-05-23"},{"cvss_score":7.8,"headline":"Linux Kernel Race Condition","id":"CVE-2025-39964","kev_date_added":"2026-09-18","published":"2025-10-13"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-10-15","vendors":["Linux"]},"summary":"An integer overflow in the Linux kernel's ECDSA crypto module can cause a denial of service when processing large key sizes.","url":"https://insights.sbomify.com/CVE-2025-37984/"}
