An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-110449 in the wild and no public exploit code.\n\nAffected product: NixOS Nix. 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-2026-110449/ (Markdown: https://insights.sbomify.com/CVE-2026-110449/index.md)","id":"CVE-2026-110449","markdown":"https://insights.sbomify.com/CVE-2026-110449/index.md","name":"CVE-2026-110449","record":{"aliases":["DEBIAN-CVE-2026-110449","GHSA-5jjg-xg55-6mw3","UBUNTU-CVE-2026-110449"],"analysis":{"component_type":"developer_tool","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Nix package manager","requires_auth":"none","summary":"An integer overflow in Nix allows out-of-bounds writes when evaluating untrusted expressions, potentially enabling code execution.","user_interaction":"not_required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:N/I:H/A:L","version":"3.1"},"cwes":[{"id":"CWE-190","name":"Integer Overflow or Wraparound"}],"description":"Nix before 2.35.3 and Lix before 2.95.4 have an integer overflow and resultant out-of-bounds write when evaluating untrusted expressions because list allocation is mishandled.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Integer overflow in Nix","id":"CVE-2026-110449","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"integer_overflow","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Privilege escalation in Nix","id":"CVE-2026-110450"},"packages":[],"prev":{"headline":"Collabora Online – Built-in CODE Server OS Command Injection","id":"CVE-2026-110447"},"products":["Nix"],"published":"2026-10-14","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"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":"2026-10-14","vendors":["NixOS"]},"summary":"An integer overflow in Nix allows out-of-bounds writes when evaluating untrusted expressions, potentially enabling code execution.","url":"https://insights.sbomify.com/CVE-2026-110449/"}
