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-2020-26558 in the wild and no public exploit code.\n\nAffected product: Debian Debian 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-2020-26558/ (Markdown: https://insights.sbomify.com/CVE-2020-26558/index.md)","id":"CVE-2020-26558","markdown":"https://insights.sbomify.com/CVE-2020-26558/index.md","name":"CVE-2020-26558","record":{"aliases":["A-174886838","ASB-A-174886838","DEBIAN-CVE-2020-26558","GHSA-7g33-jchx-2fjc","RHSA-2021:4432","UBUNTU-CVE-2020-26558"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["security_bypass","account_takeover"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Bluetooth pairing protocol","requires_auth":"none","summary":"A nearby attacker can bypass Bluetooth pairing authentication by reflecting keys to determine the Passkey bit-by-bit, allowing unauthorized device pairing.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"bluetooth_core_specification","vendor":"bluetooth"},{"product":"debian_linux","vendor":"debian"},{"product":"fedora","vendor":"fedoraproject"},{"product":"ac_1550_firmware","vendor":"intel"},{"product":"ac_3165_firmware","vendor":"intel"},{"product":"ac_3168_firmware","vendor":"intel"},{"product":"ac_7265_firmware","vendor":"intel"},{"product":"ac_8260_firmware","vendor":"intel"},{"product":"ac_8265_firmware","vendor":"intel"},{"product":"ac_9260_firmware","vendor":"intel"},{"product":"ac_9461_firmware","vendor":"intel"},{"product":"ac_9462_firmware","vendor":"intel"},{"product":"ac_9560_firmware","vendor":"intel"},{"product":"ax1650_firmware","vendor":"intel"},{"product":"ax1675_firmware","vendor":"intel"},{"product":"ax200_firmware","vendor":"intel"},{"product":"ax201_firmware","vendor":"intel"},{"product":"ax210_firmware","vendor":"intel"},{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":4.2,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:A/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-287","name":"Improper Authentication"}],"description":"Bluetooth LE and BR/EDR secure pairing in Bluetooth Core Specification 2.1 through 5.2 may permit a nearby man-in-the-middle attacker to identify the Passkey used during pairing (in the Passkey authentication procedure) by reflection of the public key and the authentication evidence of the initiating device, potentially permitting this attacker to complete authenticated pairing with the responding device using the correct Passkey for the pairing session.
