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-2026-86314 in the wild and no public exploit code.\n\nAffected product: Samsung Opensource Walrus. 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-2026-86314/ (Markdown: https://insights.sbomify.com/CVE-2026-86314/index.md)","id":"CVE-2026-86314","markdown":"https://insights.sbomify.com/CVE-2026-86314/index.md","name":"CVE-2026-86314","record":{"aliases":["GHSA-28r8-6gx4-j6mm"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"WebAssembly runtime library","requires_auth":"none","summary":"A remote attacker can cause denial of service via a crafted WebAssembly module exploiting an integer overflow in the memory bounds check.","user_interaction":"not_required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"samsung.tv_appliance","cpe":[],"cvss":{"score":6.2,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-190","name":"Integer Overflow or Wraparound"}],"description":"Integer overflow in the source-bounds check in Memory::init() (src/runtime/Memory.cpp) in Samsung walrus on all platforms allows a remote attacker to cause an out-of-bounds heap read and denial of service via a crafted WebAssembly module in which a 32-bit unsigned addition wraps around and bypasses the bounds check.\n\nThis issue affects Walrus: ff3bf5ff5c4878f8e5572c9593d303f6bc997443.","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 Walrus","id":"CVE-2026-86314","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":"Integer overflow in Escargot","id":"CVE-2026-86315"},"packages":[],"prev":{"headline":"Memory corruption in Walrus","id":"CVE-2026-86313"},"products":["Walrus"],"published":"2026-09-07","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":"2026-09-08","vendors":["Samsung Opensource"]},"summary":"A remote attacker can cause denial of service via a crafted WebAssembly module exploiting an integer overflow in the memory bounds check.","url":"https://insights.sbomify.com/CVE-2026-86314/"}
