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-2026-77178 in the wild and no public exploit code.\n\nAffected product: n/a. 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-2026-77178/ (Markdown: https://insights.sbomify.com/CVE-2026-77178/index.md)","id":"CVE-2026-77178","markdown":"https://insights.sbomify.com/CVE-2026-77178/index.md","name":"CVE-2026-77178","record":{"aliases":["GHSA-65c9-4f8q-72qc","UBUNTU-CVE-2026-77178"],"analysis":{"component_type":"operating_system","fix_type":"upgrade","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"VirtualBox hypervisor","requires_auth":"none","summary":"Guest OS users can trigger an out-of-bounds write in the host OS via the PCNet network device model, potentially leading to code execution or privilege escalation.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[],"cvss":{"score":9.1,"severity":"critical","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"}],"description":"Oracle VM VirtualBox before 7.2.8 allows guest OS users to cause an out-of-bounds write in the host OS in pcnetReceiveNoSync in DevPCNet.cpp in the PCNet (Am79C970A) network device model.","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":"Memory corruption in n/a","id":"CVE-2026-77178","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2026"},"n_packages":0,"n_references":3,"next":{"headline":"Docker Sandboxes guest can write arbitrary macOS host files via a symlink in the virtio-fs stored-path fallback","id":"CVE-2026-77179"},"packages":[],"prev":{"headline":"Code injection in n/a","id":"CVE-2026-77177"},"products":["n/a"],"published":"2026-10-06","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":"yes","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-10-06","vendors":["n/a"]},"summary":"Guest OS users can trigger an out-of-bounds write in the host OS via the PCNet network device model, potentially leading to code execution or privilege escalation.","url":"https://insights.sbomify.com/CVE-2026-77178/"}
