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-2026-80914 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-2026-80914/ (Markdown: https://insights.sbomify.com/CVE-2026-80914/index.md)","id":"CVE-2026-80914","markdown":"https://insights.sbomify.com/CVE-2026-80914/index.md","name":"CVE-2026-80914","record":{"aliases":["AZL-99959","BELL-CVE-2026-80914","DEBIAN-CVE-2026-80914","GHSA-xmw2-vj5q-xhxr","UBUNTU-CVE-2026-80914"],"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 in the Linux kernel Bluetooth ISO subsystem allows attackers to cause denial of service or execute arbitrary code via race conditions.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nBluetooth: ISO: fix use-after-free of listener socket in iso_conn_ready\n\niso_conn_ready() looks up the BIS listener socket with iso_get_sock(),\nwhich takes a reference, and then, without re-checking its state,\ncreates a child socket from it:\n\n    parent = iso_get_sock(hdev, ...);\n    if (!parent)\n        return;\n\n    lock_sock(parent);\n    sk = iso_sock_alloc(sock_net(parent), NULL, BTPROTO_ISO, ...);\n    ...\n    iso_chan_add(conn, sk, parent);\n    ...\n    release_sock(parent);\n    sock_put(parent);\n\nIf the listener socket is closed concurrently, between iso_get_sock()\nand lock_sock(), the reference taken by iso_get_sock() may be the last\none: the close path drops the link-list reference, and once\niso_conn_ready() drops its own reference at the end of the function the\nsocket is freed.
