It can only be exploited from the same machine or local network, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2025-27243 and fix it if it is affected.\n\nWhat it is: CVE-2025-27243 is a medium-severity memory corruption vulnerability in Intel(R) Ethernet Controller E810, published on 10 Feb 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-2025-27243 in the wild and no public exploit code.\n\nAffected product: Intel(R) Ethernet Controller E810. 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-2025-27243/ (Markdown: https://insights.sbomify.com/CVE-2025-27243/index.md)","id":"CVE-2025-27243","markdown":"https://insights.sbomify.com/CVE-2025-27243/index.md","name":"CVE-2025-27243","record":{"aliases":["GHSA-95x2-9xvr-3xpw"],"analysis":{"component_type":"hardware_firmware","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Intel Ethernet Controller","requires_auth":"high_privilege","summary":"A privileged local attacker can cause a denial of service via an out-of-bounds write in Intel E810 Ethernet Controller firmware.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"intel","cpe":[{"product":"ethernet_controller","vendor":"intel"}],"cvss":{"score":6.7,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:H/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"}],"description":"Out-of-bounds write in the firmware for some Intel(R) Ethernet Controller E810 before version cvl fw 1.7.8.x within Ring 0: Bare Metal OS may allow a denial of service.
