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-2026-97518 in the wild and no public exploit code.\n\nAffected product: Linux. 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-2026-97518/ (Markdown: https://insights.sbomify.com/CVE-2026-97518/index.md)","id":"CVE-2026-97518","markdown":"https://insights.sbomify.com/CVE-2026-97518/index.md","name":"CVE-2026-97518","record":{"aliases":["AZL-103592","BELL-CVE-2026-97518","DEBIAN-CVE-2026-97518","GHSA-q434-f3vh-rmc4","UBUNTU-CVE-2026-97518"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel WiFi","requires_auth":"low_privilege","summary":"A local attacker can trigger a buffer overflow in the Linux kernel WiFi subsystem by providing duplicate cipher suite entries, causing a denial of service.","user_interaction":"not_required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: cfg80211: reject duplicate wiphy cipher suite entries\n\nDuplicate entries in wiphy-\u003ecipher_suites do not describe any\nadditional capability, but cfg80211 currently accepts them and leaves\nindividual consumers to deal with them.\n\nOne such consumer is the WEXT compatibility code, which appends a WEP\nkey length for each WEP cipher entry it sees.
