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-2026-98704 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-2026-98704/ (Markdown: https://insights.sbomify.com/CVE-2026-98704/index.md)","id":"CVE-2026-98704","markdown":"https://insights.sbomify.com/CVE-2026-98704/index.md","name":"CVE-2026-98704","record":{"aliases":["AZL-108771","BELL-CVE-2026-98704","DEBIAN-CVE-2026-98704","GHSA-vrf9-cxgg-qw6c","UBUNTU-CVE-2026-98704"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["code_execution","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel","requires_auth":"none","summary":"A use-after-free in the Linux kernel Wi-Fi subsystem allows attackers to execute code or cause denial of service via crafted association responses.","user_interaction":"not_required","vuln_class":"use_after_free"},"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: mac80211: keep fallback association elements alive\n\nAssociating to a non-transmitted MBSSID profile reads freed memory while\ndetermining the operating channel and applying HT capabilities.\n\nWhen an association response omits WMM, HT, or VHT information,\nieee80211_assoc_config_link() parses the cached BSS IEs and copies the\nmissing element pointers out of that fallback parse.
