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-2021-34405 in the wild and no public exploit code.\n\nAffected product: NVIDIA SHIELD TV. 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-2021-34405/ (Markdown: https://insights.sbomify.com/CVE-2021-34405/index.md)","id":"CVE-2021-34405","markdown":"https://insights.sbomify.com/CVE-2021-34405/index.md","name":"CVE-2021-34405","record":{"aliases":["GHSA-78wc-5whv-3wwg"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"NVIDIA SHIELD TV","requires_auth":"low_privilege","summary":"An unchecked return value in the TrustZone TEE_Malloc function allows attackers to cause a denial of service on NVIDIA SHIELD TV devices.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"nvidia","cpe":[{"product":"shield_experience","vendor":"nvidia"}],"cvss":{"score":5.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-252","name":"Unchecked Return Value"}],"description":"NVIDIA Linux distributions contain a vulnerability in TrustZone’s TEE_Malloc function, where an unchecked return value causing a null pointer dereference may lead to denial of service.","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":"Null dereference in SHIELD TV","id":"CVE-2021-34405","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"null_dereference","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Race condition in SHIELD TV","id":"CVE-2021-34406"},"packages":[],"prev":{"headline":"Privilege escalation in SHIELD TV","id":"CVE-2021-34404"},"products":["SHIELD TV"],"published":"2022-01-18","related":[{"cvss_score":7.8,"headline":"Missing authorization in SHIELD TV","id":"CVE-2021-34401","kev_date_added":null,"published":"2022-01-18"},{"cvss_score":7.8,"headline":"Use after free in SHIELD TV","id":"CVE-2021-34403","kev_date_added":null,"published":"2022-01-18"},{"cvss_score":7.8,"headline":"Memory corruption in SHIELD TV","id":"CVE-2021-1068","kev_date_added":null,"published":"2021-01-20"},{"cvss_score":7.8,"headline":"Memory corruption in NVIDIA SHIELD TV","id":"CVE-2019-5699","kev_date_added":null,"published":"2019-10-09"},{"cvss_score":7.8,"headline":"Code injection in NVIDIA SHIELD TV","id":"CVE-2019-5700","kev_date_added":null,"published":"2019-10-09"},{"cvss_score":7.8,"headline":"Auth bypass in SHIELD TV","id":"CVE-2019-5679","kev_date_added":null,"published":"2019-08-06"},{"cvss_score":7.8,"headline":"Other in SHIELD TV","id":"CVE-2019-5681","kev_date_added":null,"published":"2019-08-06"}],"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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-04","vendors":["NVIDIA"]},"summary":"An unchecked return value in the TrustZone TEE_Malloc function allows attackers to cause a denial of service on NVIDIA SHIELD TV devices.","url":"https://insights.sbomify.com/CVE-2021-34405/"}
