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-2021-44732 in the wild and no public exploit code.\n\nAffected product: Arm Mbed Tls. 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-2021-44732/ (Markdown: https://insights.sbomify.com/CVE-2021-44732/index.md)","id":"CVE-2021-44732","markdown":"https://insights.sbomify.com/CVE-2021-44732/index.md","name":"CVE-2021-44732","record":{"aliases":["ALPINE-CVE-2021-44732","DEBIAN-CVE-2021-44732","GHSA-7g56-f7p4-fmcq","JLSEC-2025-214","MGASA-2022-0017","UBUNTU-CVE-2021-44732"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service","code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Mbed TLS library","requires_auth":"none","summary":"A double free vulnerability in Mbed TLS allows attackers to cause denial of service or potentially execute code via out-of-memory conditions.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"mbed_tls","vendor":"arm"},{"product":"debian_linux","vendor":"debian"},{"product":"mbed_tls","vendor":"trustedfirmware"}],"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-415","name":"Double Free"}],"description":"Mbed TLS before 3.0.1 has a double free in certain out-of-memory conditions, as demonstrated by an mbedtls_ssl_set_session() failure.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Use after free in n/a","id":"CVE-2021-44732","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"arm:mbed_tls","products":["arm:mbed_tls","debian:debian_linux"],"type":"use_after_free","year":"2021"},"n_packages":0,"n_references":7,"next":{"headline":"Use after free in n/a","id":"CVE-2021-44733"},"packages":[],"prev":{"headline":"snapd could be made to escalate privileges and run programs as administrator","id":"CVE-2021-44731"},"products":["n/a"],"published":"2021-12-20","related":[{"cvss_score":9.8,"headline":"Deserialization in n/a","id":"CVE-2026-34877","kev_date_added":null,"published":"2026-04-02"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2022-46393","kev_date_added":null,"published":"2022-12-15"},{"cvss_score":9.8,"headline":"Integer overflow in n/a","id":"CVE-2017-18187","kev_date_added":null,"published":"2018-02-14"},{"cvss_score":9.8,"headline":"Memory corruption in ARM mbed TLS before 1.3.22, before 2.1.10, and before 2.7.0","id":"CVE-2018-0487","kev_date_added":null,"published":"2018-02-13"},{"cvss_score":9.8,"headline":"Memory corruption in ARM mbed TLS before 1.3.22, before 2.1.10, and before 2.7.0","id":"CVE-2018-0488","kev_date_added":null,"published":"2018-02-13"},{"cvss_score":9.1,"headline":"Weak cryptography in n/a","id":"CVE-2026-34872","kev_date_added":null,"published":"2026-04-01"}],"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":"2025-11-03","vendors":["n/a"]},"summary":"A double free vulnerability in Mbed TLS allows attackers to cause denial of service or potentially execute code via out-of-memory conditions.","url":"https://insights.sbomify.com/CVE-2021-44732/"}
