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-2026-58008 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-2026-58008/ (Markdown: https://insights.sbomify.com/CVE-2026-58008/index.md)","id":"CVE-2026-58008","markdown":"https://insights.sbomify.com/CVE-2026-58008/index.md","name":"CVE-2026-58008","record":{"aliases":["GHSA-rp2j-q3xg-2qhf"],"analysis":{"component_type":"operating_system","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":"A stack buffer overflow in Altera Trusted Firmware allows attackers to execute arbitrary code or escalate privileges via unchecked HKDF key-size inputs.","user_interaction":"not_required","vuln_class":"memory_corruption"},"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-121","name":"Stack-based Buffer Overflow"}],"description":"Stack-based buffer overflow vulnerability in Altera Trusted Firmware on HPS allows Exploitation of Improperly Configured or Implemented Memory Protections.\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":"Unchecked HKDF key-size input in EL3 causes a stack buffer overflow","id":"CVE-2026-58008","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":"Glib: buffer over-read in glib/gvariant-serialiser.c via gvs_tuple_is_normal()","id":"CVE-2026-58010"},"packages":[],"prev":{"headline":"Unchecked SDM mailbox response address enables EL3 secure-memory corruption","id":"CVE-2026-58007"},"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":"A stack buffer overflow in Altera Trusted Firmware allows attackers to execute arbitrary code or escalate privileges via unchecked HKDF key-size inputs.","url":"https://insights.sbomify.com/CVE-2026-58008/"}
