An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-107446 in the wild and no public exploit code.\n\nAffected product: containerd overlaybd. 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-2026-107446/ (Markdown: https://insights.sbomify.com/CVE-2026-107446/index.md)","id":"CVE-2026-107446","markdown":"https://insights.sbomify.com/CVE-2026-107446/index.md","name":"CVE-2026-107446","record":{"aliases":["GHSA-x6rr-cr6c-gvp3"],"analysis":{"component_type":"container_or_infrastructure","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"containerd overlaybd","requires_auth":"none","summary":"An integer overflow in containerd overlaybd allows attackers to trigger out-of-bounds heap access via malicious registry blobs, 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":[],"cvss":{"score":6.8,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-190","name":"Integer Overflow or Wraparound"}],"description":"containerd overlaybd through 1.0.18 has a do_load_index (LSMT index loading) integer overflow (and resultant out-of-bounds heap access) for index_bytes, if an untrusted overlaybd blob from a registry is used in a scenario with multiple overlaybd-backed containers.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Integer overflow in overlaybd","id":"CVE-2026-107446","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"integer_overflow","year":"2026"},"n_packages":0,"n_references":5,"next":{"headline":"Contest Gallery \u003c 34.0.1 - Unauthenticated Vote Restriction Bypass via Spoofable Client-IP and Forgeable Voter Identity","id":"CVE-2026-107447"},"packages":[],"prev":{"headline":"Rubygem-katello: katello: katello: katello flatpak remote repositories api cross-organization authorization bypass","id":"CVE-2026-107445"},"products":["overlaybd"],"published":"2026-10-08","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":"partial"},"state":"PUBLISHED","updated":"2026-10-08","vendors":["containerd"]},"summary":"An integer overflow in containerd overlaybd allows attackers to trigger out-of-bounds heap access via malicious registry blobs, potentially leading to code execution or crashes.","url":"https://insights.sbomify.com/CVE-2026-107446/"}
