{"apiVersion":"1.0","identifier":"CVE-2026-74302","description":"In the Linux kernel, the following vulnerability has been resolved: Bluetooth: hci_core: Fix UAF in hci_unregister_dev() hci_unregister_dev() does not disable cmd_timer and ncmd_timer before the hci_dev structure is freed. If a timeout fires during device teardown, the callback dereferences freed memory (including the hdev->reset function pointer), leading to a use-after-free. Add disable_delayed_work_sync() calls alongside the existing disable_work_sync() calls to ensure both timers are fully quiesced before teardown proceeds.","publishedAt":"2026-08-15T06:22:29","lastModifiedAt":"2026-08-17T06:19:24","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-74302","cvssScore":7.8,"cvssVector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","epssProbability":0.00125,"riskScore":0.79,"affectedProduct":"Linux kernel","affectedVersions":"unknown","vulnerabilityType":"Kernel","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-74302","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-74302","en":"https://www.redsauce.net/en/cves/CVE-2026-74302","fr":"https://www.redsauce.net/fr/cves/CVE-2026-74302","pt":"https://www.redsauce.net/pt/cves/CVE-2026-74302","de":"https://www.redsauce.net/de/cves/CVE-2026-74302","sk":"https://www.redsauce.net/sk/cves/CVE-2026-74302","el":"https://www.redsauce.net/el/cves/CVE-2026-74302"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-74302"}}
