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-2026-74541 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-2026-74541/ (Markdown: https://insights.sbomify.com/CVE-2026-74541/index.md)","id":"CVE-2026-74541","markdown":"https://insights.sbomify.com/CVE-2026-74541/index.md","name":"CVE-2026-74541","record":{"aliases":["BELL-CVE-2026-74541","DEBIAN-CVE-2026-74541","GHSA-jwr7-m8vx-rqm4","UBUNTU-CVE-2026-74541"],"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 subsystem allows 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":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: clear iso_data always when detaching conn from hcon\n\nWhen setting conn-\u003ehcon = NULL, also conn-\u003ehcon-\u003eiso_data = NULL is\nnecessary, otherwise later iso_conn_free() will UAF.\n\nFix clearing of iso_data in iso_sock_disconn()\n\nFixes KASAN: slab-use-after-free in iso_conn_hold_unless_zero on\niso_sock_release() followed by hci_abort_conn_sync().","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Bluetooth: ISO: clear iso_data always when detaching conn from hcon","id":"CVE-2026-74541","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"use_after_free","year":"2026"},"n_packages":0,"n_references":5,"next":{"headline":"netfs: Fix folio_queue ENOMEM in writeback by adding a mempool","id":"CVE-2026-74542"},"packages":[],"prev":{"headline":"Bluetooth: L2CAP: fix UAF in l2cap_le_connect_rsp","id":"CVE-2026-74540"},"products":["Linux"],"published":"2026-08-15","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-10-16","vendors":["Linux"]},"summary":"A use-after-free vulnerability in the Linux kernel Bluetooth ISO subsystem allows attackers to cause denial of service or potentially execute code.","url":"https://insights.sbomify.com/CVE-2026-74541/"}
