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-2026-43062 in the wild and no public exploit code.\n\nAffected product: Linux kernel. 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-2026-43062/ (Markdown: https://insights.sbomify.com/CVE-2026-43062/index.md)","id":"CVE-2026-43062","markdown":"https://insights.sbomify.com/CVE-2026-43062/index.md","name":"CVE-2026-43062","record":{"aliases":["BELL-CVE-2026-43062","DEBIAN-CVE-2026-43062","GHSA-6mf2-xqwv-jhq3","ROOT-OS-DEBIAN-11-CVE-2026-43062","ROOT-OS-UBUNTU-2204-CVE-2026-43062","ROOT-OS-UBUNTU-2404-CVE-2026-43062","UBUNTU-CVE-2026-43062"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service","data_read"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel Bluetooth","requires_auth":"none","summary":"A type confusion in the Linux kernel Bluetooth L2CAP module causes valid packets to be rejected and incorrect data to be read, potentially leading to denial of service or information disclosure.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":7.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:L","version":"3.1"},"cwes":[{"id":"CWE-843","name":"Access of Resource Using Incompatible Type"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nBluetooth: L2CAP: Fix type confusion in l2cap_ecred_reconf_rsp()\n\nl2cap_ecred_reconf_rsp() casts the incoming data to struct\nl2cap_ecred_conn_rsp (the ECRED *connection* response, 8 bytes with\nresult at offset 6) instead of struct l2cap_ecred_reconf_rsp (2 bytes\nwith result at offset 0).\n\nThis causes two problems:\n\n - The sizeof(*rsp) length check requires 8 bytes instead of the\n   correct 2, so valid L2CAP_ECRED_RECONF_RSP packets are rejected\n   with -EPROTO.\n\n - rsp-\u003eresult reads from offset 6 instead of offset 0, returning\n   wrong data when the packet is large enough to pass the check.\n\nFix by using the correct type.
