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-2026-98462 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-2026-98462/ (Markdown: https://insights.sbomify.com/CVE-2026-98462/index.md)","id":"CVE-2026-98462","markdown":"https://insights.sbomify.com/CVE-2026-98462/index.md","name":"CVE-2026-98462","record":{"aliases":["AZL-109446","BELL-CVE-2026-98462","DEBIAN-CVE-2026-98462","GHSA-2fvm-fm9j-6jqx","UBUNTU-CVE-2026-98462"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["code_execution","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel Bluetooth","requires_auth":"none","summary":"A use-after-free vulnerability in the Linux kernel Bluetooth ISO connection handling allows local attackers to cause denial of service or potentially execute code.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nBluetooth: hci_conn: fix CIS hold ownership on reuse\n\nCommit 69997d50ec57 (\"Bluetooth: ISO: handle bound CIS cleanup via\nhci_conn\") made hci_bind_cis() and hci_connect_cis() return a\nconnection with one hold for the ISO layer.  hci_bind_cis() currently\ntakes that hold only after configuring a CIS, so its BT_CONNECTED and\nmatching BT_BOUND paths return a bare lookup result.
