MediaTek chipset, published on 3 Aug 2026. 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-2026-20469 in the wild and no public exploit code.\n\nAffected product: MediaTek, Inc. MediaTek chipset. 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-2026-20469/ (Markdown: https://insights.sbomify.com/CVE-2026-20469/index.md)","id":"CVE-2026-20469","markdown":"https://insights.sbomify.com/CVE-2026-20469/index.md","name":"CVE-2026-20469","record":{"aliases":["A-518601919","ASB-A-518601919","GHSA-97c8-m5xh-6cgp","M-AUTO00834868"],"analysis":{"component_type":"hardware_firmware","fix_type":"patch","impacts":["privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"MediaTek chipset","requires_auth":"high_privilege","summary":"Local attackers with System privileges can escalate privileges via improper input validation in trusted_mem on MediaTek chipsets.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"MediaTek","cpe":[],"cvss":{"score":6,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-123","name":"Write-what-where Condition"}],"description":"In trusted_mem, there is a possible escalation of privilege due to improper input validation.
