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-2026-34353 in the wild and no public exploit code.\n\nAffected product: OCaml. 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-2026-34353/ (Markdown: https://insights.sbomify.com/CVE-2026-34353/index.md)","id":"CVE-2026-34353","markdown":"https://insights.sbomify.com/CVE-2026-34353/index.md","name":"CVE-2026-34353","record":{"aliases":["AZL-81104","DEBIAN-CVE-2026-34353","GHSA-6p45-jv22-32gp","OESA-2026-1889","OESA-2026-1890","OESA-2026-1891","OESA-2026-1892","OESA-2026-1893","OSEC-2026-04","UBUNTU-CVE-2026-34353"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"OCaml programming language","requires_auth":"none","summary":"An integer overflow in OCaml's Bigarray.reshape allows attackers to read arbitrary memory when processing untrusted data.","user_interaction":"not_required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"ocaml","vendor":"ocaml"}],"cvss":{"score":5.9,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:H/PR:N/UI:N/S:C/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-190","name":"Integer Overflow or Wraparound"}],"description":"In OCaml through 4.14.3, Bigarray.reshape allows an integer overflow, and resultant reading of arbitrary memory, when untrusted data is processed.","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":"Integer overflow in OCaml","id":"CVE-2026-34353","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"integer_overflow","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"Race condition in Guardicore Platform Agent","id":"CVE-2026-34354"},"packages":[],"prev":{"headline":"Missing authorization in TigerVNC","id":"CVE-2026-34352"},"products":["OCaml"],"published":"2026-03-27","related":[{"cvss_score":9.8,"headline":"Integer overflow in n/a","id":"CVE-2018-9838","kev_date_added":null,"published":"2018-04-06"},{"cvss_score":9.8,"headline":"Privilege escalation in n/a","id":"CVE-2017-9772","kev_date_added":null,"published":"2017-06-23"},{"cvss_score":7.9,"headline":"Memory corruption in OCaml","id":"CVE-2026-28364","kev_date_added":null,"published":"2026-02-27"},{"cvss_score":7.8,"headline":"Other in n/a","id":"CVE-2017-9779","kev_date_added":null,"published":"2017-09-07"}],"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":"partial"},"state":"PUBLISHED","updated":"2026-03-27","vendors":["OCaml"]},"summary":"An integer overflow in OCaml's Bigarray.reshape allows attackers to read arbitrary memory when processing untrusted data.","url":"https://insights.sbomify.com/CVE-2026-34353/"}
