An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-30636 in the wild and no public exploit code.\n\nAffected product: n/a. 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-2021-30636/ (Markdown: https://insights.sbomify.com/CVE-2021-30636/index.md)","id":"CVE-2021-30636","markdown":"https://insights.sbomify.com/CVE-2021-30636/index.md","name":"CVE-2021-30636","record":{"aliases":["GHSA-gc9h-g4qm-fgcv"],"analysis":{"component_type":"iot_embedded","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"MediaTek LinkIt SDK","requires_auth":"none","summary":"An integer overflow in MediaTek LinkIt SDK memory allocation functions can lead to memory corruption, potentially allowing code execution or denial of service.","user_interaction":"not_required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"linkit_software_development_kit","vendor":"mediatek"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-190","name":"Integer Overflow or Wraparound"}],"description":"In MediaTek LinkIt SDK before 4.6.1, there is a possible memory corruption due to an integer overflow during mishandled memory allocation by pvPortCalloc and pvPortRealloc.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Integer overflow in n/a","id":"CVE-2021-30636","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"integer_overflow","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Cross-site scripting in n/a","id":"CVE-2021-30637"},"packages":[],"prev":{"headline":"Path traversal in n/a","id":"CVE-2021-30635"},"products":["n/a"],"published":"2022-01-24","related":[{"cvss_score":9.8,"headline":"Command injection in EN7528, EN7580","id":"CVE-2022-32665","kev_date_added":null,"published":"2023-01-03"},{"cvss_score":8.8,"headline":"Command injection in EN7516, EN7528, EN7529, EN7561, EN7562, EN7580","id":"CVE-2022-32664","kev_date_added":null,"published":"2023-01-03"}],"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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-03","vendors":["n/a"]},"summary":"An integer overflow in MediaTek LinkIt SDK memory allocation functions can lead to memory corruption, potentially allowing code execution or denial of service.","url":"https://insights.sbomify.com/CVE-2021-30636/"}
