CVSS 评分: 高危(8.8)  CVE ID: CVE-2026-53072


漏洞描述

In the Linux kernel, the following vulnerability has been resolved:

Bluetooth: fix locking in hci_conn_request_evt() with HCI_PROTO_DEFER

When protocol sets HCI_PROTO_DEFER, hci_conn_request_evt() calls
hci_connect_cfm(conn) without hdev->lock. Generally hci_connect_cfm()
assumes it is held, and if conn is deleted concurrently -> UAF.

Only SCO and ISO set HCI_PROTO_DEFER and only for defer setup listen,
and HCI_EV_CONN_REQUEST is not generated for ISO. In the non-deferred
listening socket code paths, hci_connect_cfm(conn) is called with
hdev->lock held.

Fix by holding the lock.
