Use of hci_conn in hci_sync callbacks also\nneeds to hold refcount to avoid UAF.\n\nTake appropriate locks for hci_conn lookups, and take refcount for\nhci_conn pointers stored in mgmt_pending_cmd so that the pointer stays\nvalid.\n\nWhen accessing conn->state, ensure hdev->lock is held to avoid data\nrace.","published":"2026-08-10T12:04:10.564Z","modified":"2026-08-14T04:04:12.865782539Z","cvss":{"score":7.8,"severity":"HIGH","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[{"ecosystem":"Linux","name":"Kernel","fixedVersion":"6.6.148"}],"fix":null,"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/b56f2ecafc08f372bf0529f9c4f3f429cb1702dc"},{"type":"WEB","url":"https://git.kernel.org/stable/c/d5b3b484b62bb0f4542e7622789d28871626cdf0"},{"type":"WEB","url":"https://git.kernel.org/stable/c/da55f570191d5d72f10c607a7043b947eb05ea46"},{"type":"WEB","url":"https://git.kernel.org/stable/c/ecdcb55ea1c01dda074406f38058785a69526734"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f915e74b6f18293d1d69a2a3305ef321ff7c0172"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/68xxx/CVE-2026-68391.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-68391"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-14T04:04:12.865782539Z"}}
