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-2024-26886 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-2024-26886/ (Markdown: https://insights.sbomify.com/CVE-2024-26886/index.md)","id":"CVE-2024-26886","markdown":"https://insights.sbomify.com/CVE-2024-26886/index.md","name":"CVE-2024-26886","record":{"aliases":["AZL-58893","BELL-CVE-2024-26886","DEBIAN-CVE-2024-26886","GHSA-46xg-2692-fh7x","ROOT-OS-DEBIAN-11-CVE-2024-26886","UBUNTU-CVE-2024-26886"],"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 deadlock in the Linux kernel Bluetooth subsystem can cause a use-after-free, leading to system denial of service.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":6.5,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-416","name":"Use After Free"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nBluetooth: af_bluetooth: Fix deadlock\n\nAttemting to do sock_lock on .recvmsg may cause a deadlock as shown\nbellow, so instead of using sock_sock this uses sk_receive_queue.lock\non bt_sock_ioctl to avoid the UAF:\n\nINFO: task kworker/u9:1:121 blocked for more than 30 seconds.\n      Not tainted 6.7.6-lemon #183\nWorkqueue: hci0 hci_rx_work\nCall Trace:\n \u003cTASK\u003e\n __schedule+0x37d/0xa00\n schedule+0x32/0xe0\n __lock_sock+0x68/0xa0\n ? __pfx_autoremove_wake_function+0x10/0x10\n lock_sock_nested+0x43/0x50\n l2cap_sock_recv_cb+0x21/0xa0\n l2cap_recv_frame+0x55b/0x30a0\n ? psi_task_switch+0xeb/0x270\n ? finish_task_switch.isra.0+0x93/0x2a0\n hci_rx_work+0x33a/0x3f0\n process_one_work+0x13a/0x2f0\n worker_thread+0x2f0/0x410\n ? __pfx_worker_thread+0x10/0x10\n kthread+0xe0/0x110\n ? __pfx_kthread+0x10/0x10\n ret_from_fork+0x2c/0x50\n ? __pfx_kthread+0x10/0x10\n ret_from_fork_asm+0x1b/0x30\n \u003c/TASK\u003e","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: af_bluetooth: Fix deadlock","id":"CVE-2024-26886","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"linux:linux_kernel","products":["linux:linux_kernel"],"type":"use_after_free","year":"2024"},"n_packages":0,"n_references":5,"next":{"headline":"Bluetooth: btusb: Fix memory leak","id":"CVE-2024-26887"},"packages":[],"prev":{"headline":"bpf: Fix DEVMAP_HASH overflow check on 32-bit arches","id":"CVE-2024-26885"},"products":["Linux"],"published":"2024-04-17","related":[{"cvss_score":8.8,"headline":"Linux Kernel Out-of-Bounds Write","id":"CVE-2026-53266","kev_date_added":"2026-09-18","published":"2026-06-25"},{"cvss_score":8.8,"headline":"Linux Kernel Improper Input Validation","id":"CVE-2013-6282","kev_date_added":"2022-09-15","published":"2013-11-19"},{"cvss_score":8.4,"headline":"Linux Kernel Heap-Based Buffer Overflow","id":"CVE-2022-0185","kev_date_added":"2024-08-21","published":"2022-02-11"},{"cvss_score":8.4,"headline":"Linux Kernel Privilege Escalation","id":"CVE-2013-2094","kev_date_added":"2022-09-15","published":"2013-05-14"},{"cvss_score":7.8,"headline":"Linux Kernel Unspecified","id":"CVE-2026-53362","kev_date_added":"2026-08-27","published":"2026-07-04"},{"cvss_score":7.8,"headline":"Linux Kernel Missing Initialization of a Variable","id":"CVE-2026-46300","kev_date_added":"2026-10-28","published":"2026-05-23"},{"cvss_score":7.8,"headline":"Linux Kernel Race Condition","id":"CVE-2025-39964","kev_date_added":"2026-09-18","published":"2025-10-13"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-06-01","vendors":["Linux"]},"summary":"A deadlock in the Linux kernel Bluetooth subsystem can cause a use-after-free, leading to system denial of service.","url":"https://insights.sbomify.com/CVE-2024-26886/"}
