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-2026-40962 in the wild and no public exploit code.\n\nAffected product: Ffmpeg Ffmpeg. 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-2026-40962/ (Markdown: https://insights.sbomify.com/CVE-2026-40962/index.md)","id":"CVE-2026-40962","markdown":"https://insights.sbomify.com/CVE-2026-40962/index.md","name":"CVE-2026-40962","record":{"aliases":["DEBIAN-CVE-2026-40962","GHSA-48wr-p98v-9w5h","JLSEC-2026-652","MINI-5289-vgw7-jmpp","MINI-8jh5-6f5v-4hw9","UBUNTU-CVE-2026-40962","openSUSE-SU-2026:10767-1","openSUSE-SU-2026:10768-1","openSUSE-SU-2026:20726-1"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Multimedia processing library","requires_auth":"none","summary":"An integer overflow in FFmpeg's CENC subsample handling allows out-of-bounds writes, potentially leading to code execution or crashes.","user_interaction":"not_required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"ffmpeg","vendor":"ffmpeg"}],"cvss":{"score":4.9,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:L","version":"3.1"},"cwes":[{"id":"CWE-190","name":"Integer Overflow or Wraparound"}],"description":"FFmpeg before 8.1 has an integer overflow and resultant out-of-bounds write via CENC (Common Encryption) subsample data to libavformat/mov.c.","ecosystems":["openSUSE:Tumbleweed"],"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":"Integer overflow in FFmpeg","id":"CVE-2026-40962","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"ffmpeg:ffmpeg","products":["ffmpeg:ffmpeg"],"type":"integer_overflow","year":"2026"},"n_packages":2,"n_references":1,"next":{"headline":"Apache Airflow: DAG authorization bypass on /ui/structure/structure_data","id":"CVE-2026-40963"},"packages":[{"ecosystem":"openSUSE:Tumbleweed","fixed":["4.4.6-12.1"],"introduced":["0"],"last_affected":[],"package":"ffmpeg-4","purl":"pkg:rpm/opensuse/ffmpeg-4\u0026distro=openSUSE%20Tumbleweed","source":"openSUSE-SU-2026:10767-1"},{"ecosystem":"openSUSE:Tumbleweed","fixed":["7.1.3-3.1"],"introduced":["0"],"last_affected":[],"package":"ffmpeg-7","purl":"pkg:rpm/opensuse/ffmpeg-7\u0026distro=openSUSE%20Tumbleweed","source":"openSUSE-SU-2026:10768-1"}],"prev":{"headline":"Apache Airflow: Open Redirect Bypass Vulnerability","id":"CVE-2026-40961"},"products":["FFmpeg"],"published":"2026-04-16","related":[{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2013-0864","kev_date_added":null,"published":"2013-11-23"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2013-0872","kev_date_added":null,"published":"2013-11-23"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2013-0873","kev_date_added":null,"published":"2013-11-23"},{"cvss_score":10,"headline":"Null dereference in n/a","id":"CVE-2013-4265","kev_date_added":null,"published":"2013-11-23"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2011-3937","kev_date_added":null,"published":"2013-01-05"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2012-2772","kev_date_added":null,"published":"2012-09-10"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2012-2775","kev_date_added":null,"published":"2012-09-10"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"SUSE","prefix":"openSUSE"},{"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":"2026-04-16","vendors":["FFmpeg"]},"summary":"An integer overflow in FFmpeg's CENC subsample handling allows out-of-bounds writes, potentially leading to code execution or crashes.","url":"https://insights.sbomify.com/CVE-2026-40962/"}
