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-2026-56211 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-2026-56211/ (Markdown: https://insights.sbomify.com/CVE-2026-56211/index.md)","id":"CVE-2026-56211","markdown":"https://insights.sbomify.com/CVE-2026-56211/index.md","name":"CVE-2026-56211","record":{"aliases":["DEBIAN-CVE-2026-56211","ECHO-5509-692b-aa69","GHSA-qr4p-j2pf-4w4x","ROOT-OS-DEBIAN-11-CVE-2026-56211","UBUNTU-CVE-2026-56211"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":true,"product_category":"AV1 codec library","requires_auth":"none","summary":"Remote attackers can execute arbitrary code by sending crafted video frames to services using libaom with SVC encoding 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:H/PR:N/UI:R/S:U/C:L/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"}],"description":"A remote code execution vulnerability was found in libaom, the reference AV1 codec implementation. Insufficient bounds validation in the AV1 encoder's SVC (Scalable Video Coding) layer ID control allows an attacker to supply crafted video frame pixels that overlap with internal encoder layer context structures. In fork-based video processing services, an attacker can use this to hijack the cyclic refresh map pointer, brute-force the process base address via a crash oracle, and redirect control flow to achieve arbitrary command execution. Exploitation requires the target service to use libaom with SVC encoding enabled and accept attacker-supplied video frames.","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: remote code execution via svc layer context handling with attacker-controlled frames","id":"CVE-2026-56211","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":"Capgo - Improper 2FA Enforcement Logic via Team Security Settings","id":"CVE-2026-56212"},"packages":[],"prev":{"headline":"Libaom: libaom: heap-buffer-overflow read via missing bounds check in ctrl_set_layer_id","id":"CVE-2026-56210"},"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":"Remote attackers can execute arbitrary code by sending crafted video frames to services using libaom with SVC encoding enabled.","url":"https://insights.sbomify.com/CVE-2026-56211/"}
