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-2026-80943 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-2026-80943/ (Markdown: https://insights.sbomify.com/CVE-2026-80943/index.md)","id":"CVE-2026-80943","markdown":"https://insights.sbomify.com/CVE-2026-80943/index.md","name":"CVE-2026-80943","record":{"aliases":["BELL-CVE-2026-80943","DEBIAN-CVE-2026-80943","GHSA-8f9m-rj4x-3w9p","UBUNTU-CVE-2026-80943"],"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 driver","requires_auth":"none","summary":"An out-of-bounds array access in the rtl8192du WiFi driver allows attackers to cause a denial of service via crafted QoS TID values.","user_interaction":"not_required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":7.6,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:H","version":"3.1"},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: rtlwifi: rtl8192du: check QoS TID before indexing tids\n\nrtl92du_tx_fill_desc() uses ieee80211_get_tid() to read the QoS TID\nfrom the 802.11 header and then uses it as an index into\nsta_entry-\u003etids[]. ieee80211_get_tid() returns the low 4-bit QoS TID\nvalue, so the result can be in the range 0..15.\n\nrtlwifi only allocates MAX_TID_COUNT entries for sta_entry-\u003etids[], and\nMAX_TID_COUNT is 9.
