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-2026-79831 in the wild and no public exploit code.\n\nAffected product: Hewlett Packard Enterprise HPE NonStop Posix User Threads. 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-2026-79831/ (Markdown: https://insights.sbomify.com/CVE-2026-79831/index.md)","id":"CVE-2026-79831","markdown":"https://insights.sbomify.com/CVE-2026-79831/index.md","name":"CVE-2026-79831","record":{"aliases":["GHSA-5wpv-46m6-vrc3"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"HPE NonStop OS","requires_auth":"low_privilege","summary":"A heap buffer overflow in HPE NonStop Posix User Threads allows attackers to execute arbitrary code on the system.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"hpe","cpe":[],"cvss":{"score":6.6,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:H","version":"3.1"},"cwes":[{"id":"CWE-122","name":"Heap-based Buffer Overflow"}],"description":"A heap buffer overflow in HPE NonStop Posix User Threads may allow arbitrary code execution.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"HPE NonStop Posix User Threads - Heap buffer overflow vulnerability","id":"CVE-2026-79831","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"HPE NonStop SQL/MX Executor - Buffer overflow vulnerability","id":"CVE-2026-79832"},"packages":[],"prev":{"headline":"HPE NonStop Kernel Level Thread Model Lib - Stack buffer overflow vulnerability","id":"CVE-2026-79830"},"products":["HPE NonStop Posix User Threads"],"published":"2026-10-15","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":"2026-10-15","vendors":["Hewlett Packard Enterprise"]},"summary":"A heap buffer overflow in HPE NonStop Posix User Threads allows attackers to execute arbitrary code on the system.","url":"https://insights.sbomify.com/CVE-2026-79831/"}
