It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link."},"fix_prompt":"Check this codebase for CVE-2023-40218 and fix it if it is affected.\n\nWhat it is: CVE-2023-40218 is a low-severity vulnerability in Samsung Exynos 1280 Firmware, published on 12 Sep 2023. It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2023-40218 in the wild and no public exploit code.\n\nAffected product: Samsung Exynos 1280 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-2023-40218/ (Markdown: https://insights.sbomify.com/CVE-2023-40218/index.md)","id":"CVE-2023-40218","markdown":"https://insights.sbomify.com/CVE-2023-40218/index.md","name":"CVE-2023-40218","record":{"aliases":["GHSA-rc82-xg8f-27pw"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["privilege_escalation","code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Samsung Exynos NPU driver","requires_auth":"high_privilege","summary":"A crafted application can exploit an integer overflow in the Samsung Exynos NPU kernel driver to bypass error checks, potentially leading to privilege escalation or code execution.","user_interaction":"required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"exynos_1280_firmware","vendor":"samsung"},{"product":"exynos_1380_firmware","vendor":"samsung"},{"product":"exynos_2100_firmware","vendor":"samsung"},{"product":"exynos_2200_firmware","vendor":"samsung"},{"product":"exynos_980_firmware","vendor":"samsung"},{"product":"exynos_9820_firmware","vendor":"samsung"}],"cvss":{"score":2,"severity":"low","source":"cna","vector":"CVSS:3.1/AC:L/AV:L/A:L/C:N/I:N/PR:H/S:U/UI:R","version":"3.1"},"cwes":[{"id":"CWE-190","name":"Integer Overflow or Wraparound"}],"description":"An issue was discovered in the NPU kernel driver in Samsung Exynos Mobile Processor 9820, 980, 2100, 2200, 1280, and 1380.
