the Linux kernel, the following vulnerability has been resolved:\n\nBluetooth: serialize accept_q access\n\nbt_sock_poll() walks the accept queue without synchronization, while\nchild teardown can unlink the same socket and drop its last reference.\nThe unsynchronized accept queue walk has existed since the initial\nBluetooth import.\n\nProtect accept_q with a dedicated lock for queue updates and polling.\nAlso rework bt_accept_dequeue() to take temporary child references under\nthe queue lock before dropping it and locking the child socket.","published_at":"2026-06-24T07:14:14.539000Z","last_modified_at":null,"cvss_v3_score":8.8,"cvss_v3_vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","cvss_v3_severity":"HIGH","cvss_v4_score":null,"cvss_v4_vector":null,"cvss_v4_severity":null,"ssvc_decision":null,"ssvc_exploitation":null,"ssvc_automatable":null,"ssvc_technical_impact":null,"cwes":null,"nvd_references":["https://git.kernel.org/stable/c/d9ce4de05df2385c19e2c7d12f529144e1a44af1","https://git.kernel.org/stable/c/41c8c1c7923e86e0eb59cfb4279349112756a336","https://git.kernel.org/stable/c/4ec17782fd186f901a7329605d11048b085b945a","https://git.kernel.org/stable/c/be43e6b4043113c3b3cf887c3c8350f67140274c","https://git.kernel.org/stable/c/85f8674cae82053f1e6bab295f6a8422cca14db5","https://git.kernel.org/stable/c/8b4c412e001b0c670eb937beab491af974da55b3","https://git.kernel.org/stable/c/a218bf69eb51fefe59a3976fa8925261141f681c","https://git.kernel.org/stable/c/e83f5e24da741fa9405aeeff00b08c5ee7c37b88"],"vuln_status":null,"trending_score":null,"is_trending":false,"has_trended":false,"trended_number_one":false,"trending_peak_score":null,"trending_peak_rank":null,"started_trending_at":null,"trended_number_one_at":null,"summary_generated":null,"summary_generated_at":null,"summary_model":null,"created_at":"2026-06-28T17:55:22.518073Z","updated_at":"2026-06-28T23:30:49.088205Z"},"effective_severity":"HIGH","badges":[],"impact_analysis":[],"cvss_v3_decoded":{"version":"3.1","metrics":[{"metric":"AV","name":"Attack
