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-2026-98184 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-2026-98184/ (Markdown: https://insights.sbomify.com/CVE-2026-98184/index.md)","id":"CVE-2026-98184","markdown":"https://insights.sbomify.com/CVE-2026-98184/index.md","name":"CVE-2026-98184","record":{"aliases":["BELL-CVE-2026-98184","DEBIAN-CVE-2026-98184","GHSA-m63w-cm3m-w2gf","UBUNTU-CVE-2026-98184"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel driver","requires_auth":"high_privilege","summary":"A local attacker with CAP_NET_ADMIN can trigger a heap buffer overflow in the mwifiex Wi-Fi driver via integer truncation, potentially leading to code execution or privilege escalation.","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: mwifiex: prevent authentication frame length truncation\n\nmwifiex_cfg80211_authenticate() derives the authentication frame length\nfrom req-\u003eie_len and req-\u003eauth_data_len, both of type size_t, but stores\nit in a u16.\n\nNL80211_ATTR_AUTH_DATA only has a minimum length policy.
