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-2026-46138 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-2026-46138/ (Markdown: https://insights.sbomify.com/CVE-2026-46138/index.md)","id":"CVE-2026-46138","markdown":"https://insights.sbomify.com/CVE-2026-46138/index.md","name":"CVE-2026-46138","record":{"aliases":["AZL-89130","BELL-CVE-2026-46138","DEBIAN-CVE-2026-46138","GHSA-wf79-2h53-8gvp","ROOT-OS-UBUNTU-2404-CVE-2026-46138","UBUNTU-CVE-2026-46138"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel Bluetooth","requires_auth":"none","summary":"A missing bounds check in the Linux kernel Bluetooth driver allows a malicious controller to trigger an out-of-bounds read and infinite loop, causing a system hang.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":8.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nBluetooth: hci_event: Fix OOB read and infinite loop in hci_le_create_big_complete_evt\n\nhci_le_create_big_complete_evt() iterates over BT_BOUND connections for\na BIG handle using a while loop, accessing ev-\u003ebis_handle[i++] on each\niteration.
