Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2024-32018 in the wild and no public exploit code.\n\nAffected product: RIOT-OS RIOT. 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-2024-32018/ (Markdown: https://insights.sbomify.com/CVE-2024-32018/index.md)","id":"CVE-2024-32018","markdown":"https://insights.sbomify.com/CVE-2024-32018/index.md","name":"CVE-2024-32018","record":{"aliases":["GHSA-899m-q6pp-hmp3"],"analysis":{"component_type":"operating_system","fix_type":"workaround","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":true,"product_category":"RIOT OS","requires_auth":"low_privilege","summary":"Attackers can trigger a buffer overflow in RIOT OS by providing oversized input when assertions are disabled, potentially leading to code execution or denial of service.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"riot","vendor":"riot-os"}],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-120","name":"Buffer Copy without Checking Size of Input"}],"description":"RIOT is a real-time multi-threading operating system that supports a range of devices that are typically 8-bit, 16-bit and 32-bit microcontrollers. Most codebases define assertion macros which compile to a no-op on non-debug builds. If assertions are the only line of defense against untrusted input, the software may be exposed to attacks that leverage the lack of proper input checks. In detail, in the `nimble_scanlist_update()` function below, `len` is checked in an assertion and subsequently used in a call to `memcpy()`. If an attacker is able to provide a larger `len` value while assertions are compiled-out, they can write past the end of the fixed-length `e-\u003ead` buffer. If the unchecked input above is attacker-controlled and crosses a security boundary, the impact of the buffer overflow vulnerability could range from denial of service to arbitrary code execution. This issue has not yet been patched. Users are advised to add manual `len` checking.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Ineffective size check due to assert() and buffer overflow in RIOT","id":"CVE-2024-32018","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2024"},"n_packages":0,"n_references":4,"next":{"headline":"ndsudo: local privilege escalation via untrusted search path","id":"CVE-2024-32019"},"packages":[],"prev":{"headline":"Buffer overflows in RIOT","id":"CVE-2024-32017"},"products":["RIOT"],"published":"2024-05-01","related":[{"cvss_score":9.8,"headline":"Buffer overflows in RIOT","id":"CVE-2024-32017","kev_date_added":null,"published":"2024-05-01"},{"cvss_score":9.8,"headline":"RIOT-OS vulnerable to Out of Bounds Write in _rbuf_add","id":"CVE-2023-33975","kev_date_added":null,"published":"2023-05-30"},{"cvss_score":9.8,"headline":"RIOT-OS vulnerable to Buffer Overflow during IPHC receive","id":"CVE-2023-24819","kev_date_added":null,"published":"2023-04-24"},{"cvss_score":9.8,"headline":"RIOT-OS vulnerable to Packet Type Confusion during IPHC send","id":"CVE-2023-24823","kev_date_added":null,"published":"2023-04-24"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2021-27357","kev_date_added":null,"published":"2021-04-06"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2021-27697","kev_date_added":null,"published":"2021-04-06"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2021-27698","kev_date_added":null,"published":"2021-04-06"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"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":"2025-02-13","vendors":["RIOT-OS"]},"summary":"Attackers can trigger a buffer overflow in RIOT OS by providing oversized input when assertions are disabled, potentially leading to code execution or denial of service.","url":"https://insights.sbomify.com/CVE-2024-32018/"}
