It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-90508 exists.\n\nAffected product: Chengdu Qilu Technology Ludashi. 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-2026-90508/ (Markdown: https://insights.sbomify.com/CVE-2026-90508/index.md)","id":"CVE-2026-90508","markdown":"https://insights.sbomify.com/CVE-2026-90508/index.md","name":"CVE-2026-90508","record":{"aliases":["GHSA-4jv3-g8rw-vxw2"],"analysis":{"component_type":"operating_system","fix_type":"no_fix_stated","impacts":["privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Ludashi security driver","requires_auth":"high_privilege","summary":"Local attackers can exploit missing authorization in the Ludashi kernel driver to escalate privileges, posing a significant risk to system integrity.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulDB","cpe":[],"cvss":{"score":4.6,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:H/UI:N/VC:N/VI:L/VA:L/SC:N/SI:N/SA:N/E:P","version":"4.0"},"cwes":[{"id":"CWE-863","name":"Incorrect Authorization"},{"id":"CWE-862","name":"Missing Authorization"}],"description":"A security flaw has been discovered in Chengdu Qilu Technology Ludashi 6.1026.4715.714.
