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-2026-13466 in the wild and no public exploit code.\n\nAffected product: Altera Trusted Firmware. 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-2026-13466/ (Markdown: https://insights.sbomify.com/CVE-2026-13466/index.md)","id":"CVE-2026-13466","markdown":"https://insights.sbomify.com/CVE-2026-13466/index.md","name":"CVE-2026-13466","record":{"aliases":["GHSA-h785-rv9q-vrg6"],"analysis":{"component_type":"hardware_firmware","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Altera Trusted Firmware","requires_auth":"high_privilege","summary":"An integer overflow in Altera Trusted Firmware allows buffer overflows, potentially enabling code execution or privilege escalation on HPS systems.","user_interaction":"not_required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Altera","cpe":[],"cvss":{"score":8.3,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:H/UI:N/VC:L/VI:H/VA:H/SC:L/SI:H/SA:H","version":"4.0"},"cwes":[{"id":"CWE-131","name":"Incorrect Calculation of Buffer Size"}],"description":"Incorrect calculation of buffer size vulnerability in Altera Trusted Firmware on HPS allows Overflow Buffers.\n\nThis issue affects Trusted Firmware: through socfpga_v2.14.0.","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":"Unit Confusion in VAB Authentication","id":"CVE-2026-13466","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":"Systemic Missing Address Validation in SiP SMC Handlers","id":"CVE-2026-13467"},"packages":[],"prev":{"headline":"EL3 Stack Buffer Overflow in FCS HKDF Request","id":"CVE-2026-13465"},"products":["Trusted Firmware"],"published":"2026-09-24","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":"2026-09-24","vendors":["Altera"]},"summary":"An integer overflow in Altera Trusted Firmware allows buffer overflows, potentially enabling code execution or privilege escalation on HPS systems.","url":"https://insights.sbomify.com/CVE-2026-13466/"}
