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-2026-64835 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-2026-64835/ (Markdown: https://insights.sbomify.com/CVE-2026-64835/index.md)","id":"CVE-2026-64835","markdown":"https://insights.sbomify.com/CVE-2026-64835/index.md","name":"CVE-2026-64835","record":{"aliases":["DEBIAN-CVE-2026-64835","ECHO-8b20-d6e3-e563","GHSA-p2v8-4c4f-rwpq","JLSEC-2026-1177","MINI-gh6x-w3f4-qm2r","UBUNTU-CVE-2026-64835"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Multimedia processing library","requires_auth":"none","summary":"Attackers can trigger out-of-bounds memory access in FFmpeg's ADX decoder via crafted audio files, potentially leading to code execution or crashes.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[{"product":"ffmpeg","vendor":"ffmpeg"}],"cvss":{"score":8.7,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"}],"description":"FFmpeg versions 4.4 through 8.1.2 contain an out-of-bounds memory access vulnerability in the ADX audio decoder within libavcodec/adxdec.c that allows attackers to trigger both out-of-bounds reads and writes by supplying a crafted ADX or AAX audio file with a mid-stream channel layout change.
