An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2023-38538 in the wild and no public exploit code.\n\nAffected product: Facebook WhatsApp Business for Android. 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-2023-38538/ (Markdown: https://insights.sbomify.com/CVE-2023-38538/index.md)","id":"CVE-2023-38538","markdown":"https://insights.sbomify.com/CVE-2023-38538/index.md","name":"CVE-2023-38538","record":{"aliases":["GHSA-hr72-3p79-rchw"],"analysis":{"component_type":"mobile_application","fix_type":"patch","impacts":["denial_of_service","code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"WhatsApp messaging app","requires_auth":"none","summary":"A race condition in WhatsApp's event subsystem causes a heap use-after-free, potentially leading to app crashes or unexpected control flow during calls.","user_interaction":"required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"facebook","cpe":[{"product":"whatsapp","vendor":"whatsapp"}],"cvss":{"score":5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:L/I:L/A:L/E:U/RL:O/RC:C","version":"3.1"},"cwes":[{"id":"CWE-362","name":"Concurrent Execution using Shared Resource with Improper Synchronization"}],"description":"A race condition in an event subsystem led to a heap use-after-free issue in established audio/video calls that could have resulted in app termination or unexpected control flow with very low probability.","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":"Use after free in WhatsApp Business for Android","id":"CVE-2023-38538","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"use_after_free","year":"2023"},"n_packages":0,"n_references":1,"next":{"headline":"This CVE ID has been rejected or withdrawn by its CVE Numbering Authority because it is Unused","id":"CVE-2023-38539"},"packages":[],"prev":{"headline":"Use after free in WhatsApp Business for Android","id":"CVE-2023-38537"},"products":["WhatsApp Business for Android","WhatsApp Business for iOS","WhatsApp Desktop for Mac","WhatsApp Desktop for Windows","WhatsApp for Android","WhatsApp for iOS"],"published":"2023-10-04","related":[{"cvss_score":9.8,"headline":"WhatsApp VOIP Stack Buffer Overflow","id":"CVE-2019-3568","kev_date_added":"2022-04-19","published":"2019-05-14"},{"cvss_score":8.2,"headline":"WhatsApp Cross-Site Scripting","id":"CVE-2019-18426","kev_date_added":"2022-05-23","published":"2020-01-21"},{"cvss_score":5.4,"headline":"Meta Platforms WhatsApp Incorrect Authorization","id":"CVE-2025-55177","kev_date_added":"2025-09-02","published":"2025-08-29"},{"cvss_score":9.8,"headline":"Integer overflow in WhatsApp Business for Android","id":"CVE-2022-36934","kev_date_added":null,"published":"2022-09-22"},{"cvss_score":9.8,"headline":"Memory corruption in WhatsApp Business for Android","id":"CVE-2021-24042","kev_date_added":null,"published":"2022-01-04"},{"cvss_score":9.8,"headline":"Memory corruption in WhatsApp Business for Android","id":"CVE-2021-24041","kev_date_added":null,"published":"2021-12-07"},{"cvss_score":9.8,"headline":"Memory corruption in WhatsApp Business for Android","id":"CVE-2021-24026","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":"partial"},"state":"PUBLISHED","updated":"2024-09-19","vendors":["Facebook"]},"summary":"A race condition in WhatsApp's event subsystem causes a heap use-after-free, potentially leading to app crashes or unexpected control flow during calls.","url":"https://insights.sbomify.com/CVE-2023-38538/"}
