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-2026-56209 in the wild and no public exploit code.\n\nAffected product: Red Hat AI Inference Server. 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-2026-56209/ (Markdown: https://insights.sbomify.com/CVE-2026-56209/index.md)","id":"CVE-2026-56209","markdown":"https://insights.sbomify.com/CVE-2026-56209/index.md","name":"CVE-2026-56209","record":{"aliases":["DEBIAN-CVE-2026-56209","ECHO-2e12-e6da-9a4b","GHSA-8vmr-q5h8-3vc5","ROOT-OS-DEBIAN-11-CVE-2026-56209","UBUNTU-CVE-2026-56209"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":true,"product_category":"AV1 codec library","requires_auth":"none","summary":"Attackers can achieve arbitrary code execution or denial of service by exploiting a missing bounds check in the libaom AV1 encoder when SVC is enabled.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[],"cvss":{"score":7.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:H","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"}],"description":"An arbitrary address write vulnerability was found in libaom, the reference AV1 codec implementation. A missing bounds check in the SVC (Scalable Video Coding) layer ID control function allows an attacker to inject an arbitrary pointer into the cyclic refresh map field via crafted image pixel values. The encoder then writes approximately 1,200 bytes at the attacker-controlled address. This is fully deterministic and does not require a separate information leak. An attacker who can supply frames to a network-facing libaom encoder with SVC enabled could exploit this for denial of service or potential code execution.","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":"Libaom: libaom: arbitrary address write via svc layer context oob and cyclic refresh map pointer hijack","id":"CVE-2026-56209","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2026"},"n_packages":0,"n_references":52,"next":{"headline":"Libaom: libaom: heap-buffer-overflow read via missing bounds check in ctrl_set_layer_id","id":"CVE-2026-56210"},"packages":[],"prev":{"headline":"Libaom: libaom: heap buffer overflow in av1 encoder first-pass stats buffer via lap mode","id":"CVE-2026-56208"},"products":["Red Hat AI Inference Server","Red Hat AI Inference Server 3.2","Red Hat AI Inference Server 3.3","Red Hat Enterprise Linux 10","Red Hat Enterprise Linux 9","Red Hat Enterprise Linux AI 3.3","Red Hat Enterprise Linux AI 3.3 for RHEL 9","Red Hat Enterprise Linux AI 3.4 for RHEL 9","Red Hat Enterprise Linux AI 3.5 for RHEL 9","Red Hat Hardened Images","Red Hat OpenShift AI (RHOAI)","Red Hat OpenShift AI 3.3","Red Hat OpenShift AI 3.4","Red Hat OpenShift AI 3.5"],"published":"2026-06-19","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"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":"total"},"state":"PUBLISHED","updated":"2026-10-19","vendors":["Red Hat"]},"summary":"Attackers can achieve arbitrary code execution or denial of service by exploiting a missing bounds check in the libaom AV1 encoder when SVC is enabled.","url":"https://insights.sbomify.com/CVE-2026-56209/"}
