It can only be exploited from the same machine or local network, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2026-84854 and fix it if it is affected.\n\nWhat it is: CVE-2026-84854 is a high-severity memory corruption vulnerability in wibu-systems-ag wibukey, published on 6 Oct 2026. It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-84854 in the wild and no public exploit code.\n\nAffected product: wibu-systems-ag wibukey. 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-2026-84854/ (Markdown: https://insights.sbomify.com/CVE-2026-84854/index.md)","id":"CVE-2026-84854","markdown":"https://insights.sbomify.com/CVE-2026-84854/index.md","name":"CVE-2026-84854","record":{"aliases":["GHSA-pc55-w49m-q7wf"],"analysis":{"component_type":"operating_system","fix_type":"upgrade","impacts":["denial_of_service","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"WibuKey Windows driver","requires_auth":"low_privilege","summary":"A local attacker can trigger an out-of-bounds write in the WibuKey Windows driver, causing a system crash or potential kernel memory modification.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"wibu","cpe":[],"cvss":{"score":7,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"}],"description":"In the WibuKey driver for Windows below Version 6.72, insufficient validation of user input when calculating the size of a kernel buffer could cause small amounts of data to be written outside the intended kernel buffer.
