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-2025-26403 in the wild and no public exploit code.\n\nAffected product: Intel(R) Xeon(R) 6 processors when using Intel(R) SGX or Intel(R) TDX. 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-2025-26403/ (Markdown: https://insights.sbomify.com/CVE-2025-26403/index.md)","id":"CVE-2025-26403","markdown":"https://insights.sbomify.com/CVE-2025-26403/index.md","name":"CVE-2025-26403","record":{"aliases":["ALPINE-CVE-2025-26403","BELL-CVE-2025-26403","DEBIAN-CVE-2025-26403","GHSA-7gf7-6hqr-6chr","UBUNTU-CVE-2025-26403"],"analysis":{"component_type":"hardware_firmware","fix_type":"patch","impacts":["privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"Intel Xeon processors","requires_auth":"high_privilege","summary":"A privileged local attacker can exploit an out-of-bounds write in Intel Xeon SGX/TDX memory subsystems to escalate privileges.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"intel","cpe":[],"cvss":{"score":4.5,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:L/AC:H/AT:N/PR:H/UI:N/VC:N/VI:N/VA:N/SC:H/SI:H/SA:N","version":"4.0"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"}],"description":"Out-of-bounds write in the memory subsystem for some Intel(R) Xeon(R) 6 processors when using Intel(R) SGX or Intel(R) TDX may allow a privileged user to potentially enable escalation of privilege via local access.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Memory corruption in Intel(R) Xeon(R) 6 processors when using Intel(R) SGX or Intel(R) TDX","id":"CVE-2025-26403","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2025"},"n_packages":0,"n_references":1,"next":{"headline":"Privilege escalation in Intel(R) DSA software","id":"CVE-2025-26404"},"packages":[],"prev":{"headline":"Denial of service in Intel(R) NPU Drivers","id":"CVE-2025-26402"},"products":["Intel(R) Xeon(R) 6 processors when using Intel(R) SGX or Intel(R) TDX"],"published":"2025-08-12","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":"total"},"state":"PUBLISHED","updated":"2026-02-26","vendors":["n/a"]},"summary":"A privileged local attacker can exploit an out-of-bounds write in Intel Xeon SGX/TDX memory subsystems to escalate privileges.","url":"https://insights.sbomify.com/CVE-2025-26403/"}
