It can only be exploited from the same machine or local network, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2021-26257 and fix it if it is affected.\n\nWhat it is: CVE-2021-26257 is a medium-severity denial of service vulnerability in Intel(R) Wireless Bluetooth(R) and Killer(TM) Bluetooth(R) products, published on 18 Aug 2022. 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-2021-26257 in the wild and no public exploit code.\n\nAffected product: Intel(R) Wireless Bluetooth(R) and Killer(TM) Bluetooth(R) products. 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-2021-26257/ (Markdown: https://insights.sbomify.com/CVE-2021-26257/index.md)","id":"CVE-2021-26257","markdown":"https://insights.sbomify.com/CVE-2021-26257/index.md","name":"CVE-2021-26257","record":{"aliases":["GHSA-x3gx-7gmp-75hw"],"analysis":{"component_type":"hardware_firmware","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Intel Bluetooth firmware","requires_auth":"low_privilege","summary":"An authenticated local attacker can cause a denial of service in Intel and Killer Bluetooth firmware due to improper buffer restrictions.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"intel","cpe":[{"product":"dual_band_wireless-ac_3165_firmware","vendor":"intel"},{"product":"dual_band_wireless-ac_3168_firmware","vendor":"intel"},{"product":"dual_band_wireless-ac_8260_firmware","vendor":"intel"},{"product":"dual_band_wireless-ac_8265_firmware","vendor":"intel"},{"product":"killer_wi-fi_6_ax1650_firmware","vendor":"intel"},{"product":"killer_wi-fi_6e_ax1675_firmware","vendor":"intel"},{"product":"killer_wi-fi_6e_ax1690_firmware","vendor":"intel"},{"product":"killer_wireless-ac_1550_firmware","vendor":"intel"},{"product":"wi-fi_6_ax200_firmware","vendor":"intel"},{"product":"wi-fi_6_ax201_firmware","vendor":"intel"},{"product":"wi-fi_6_ax210_firmware","vendor":"intel"},{"product":"wi-fi_6_ax211_firmware","vendor":"intel"},{"product":"wi-fi_6_ax411_firmware","vendor":"intel"},{"product":"wireless-ac_9260_firmware","vendor":"intel"},{"product":"wireless-ac_9461_firmware","vendor":"intel"},{"product":"wireless-ac_9462_firmware","vendor":"intel"},{"product":"wireless-ac_9560_firmware","vendor":"intel"},{"product":"wireless_7265_firmware","vendor":"intel"}],"cvss":{"score":5.5,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-119","name":"Improper Restriction of Operations within the Bounds of a Memory Buffer"}],"description":"Improper buffer restrictions in firmware for some Intel(R) Wireless Bluetooth(R) and Killer(TM) Bluetooth(R) products before version 22.120 may allow an authenticated user to potentially enable denial of service via local access.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Denial of service in Intel(R) Wireless Bluetooth(R) and Killer(TM) Bluetooth(R) products","id":"CVE-2021-26257","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Privilege escalation in Intel(R) Killer(TM) Control Center software","id":"CVE-2021-26258"},"packages":[],"prev":{"headline":"WordPress Survey Maker plugin \u003c= 2.0.6 -
