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-2026-74411 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-2026-74411/ (Markdown: https://insights.sbomify.com/CVE-2026-74411/index.md)","id":"CVE-2026-74411","markdown":"https://insights.sbomify.com/CVE-2026-74411/index.md","name":"CVE-2026-74411","record":{"aliases":["BELL-CVE-2026-74411","DEBIAN-CVE-2026-74411","GHSA-75cw-hg5p-hxfv","UBUNTU-CVE-2026-74411"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel Wi-Fi driver","requires_auth":"none","summary":"An integer overflow in the rtw89 Wi-Fi driver causes an infinite loop during 6GHz scanning, leading to a system panic and denial of service.","user_interaction":"not_required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: rtw89: Correct data type for scan index to avoid infinite loop\n\nA kernel soft lockup was observed during Wi-Fi scanning on the 6GHz band.\nThe CPU becomes stuck in rtw89_hw_scan_add_chan_ax for over 20 seconds,\nleading to a system panic.\n\nRIP points to 0f b6 c3 (movzbl %bl, %eax), which zero-extends\nthe low 8 bits of RBX into RAX.\nRBX (the counter i) has reached a huge value: 0x137466a1.\n\n  watchdog: BUG: soft lockup - CPU#2 stuck for 26s!
