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-2026-76663 in the wild and no public exploit code.\n\nAffected product: Hewlett Packard Enterprise HPE NonStop TELSERV. 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-2026-76663/ (Markdown: https://insights.sbomify.com/CVE-2026-76663/index.md)","id":"CVE-2026-76663","markdown":"https://insights.sbomify.com/CVE-2026-76663/index.md","name":"CVE-2026-76663","record":{"aliases":["GHSA-9rwj-hh6p-x6gp"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"HPE NonStop TELSERV","requires_auth":"none","summary":"A stack-based buffer overflow in HPE NonStop TELSERV allows attackers to cause memory corruption and denial of service.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"hpe","cpe":[],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-121","name":"Stack-based Buffer Overflow"}],"description":"A stack-based buffer overflow vulnerability in HPE NonStop TELSERV can cause memory corruption that may result in DoS.","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 TELSERV - Memory corruption vulnerability","id":"CVE-2026-76663","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 EXPAND - Out-of-Bounds memory read/write","id":"CVE-2026-76664"},"packages":[],"prev":{"headline":"HPE NonStop TELSERV - Memory corruption vulnerability","id":"CVE-2026-76662"},"products":["HPE NonStop TELSERV"],"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":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-10-15","vendors":["Hewlett Packard Enterprise"]},"summary":"A stack-based buffer overflow in HPE NonStop TELSERV allows attackers to cause memory corruption and denial of service.","url":"https://insights.sbomify.com/CVE-2026-76663/"}
