kernel: Bluetooth: mgmt: hold reference for hci_conn in mgmt_pending_cmds
zetlyn/cve-redhat · 2026-08-10
cvss 7 cwe CWE-911 packages kernel-0:5.14.0-687.50.1.el9_8, kernel-0:6.12.0-211.58.1.el10_2 severity moderate source
In the Linux kernel, the following vulnerability has been resolved: Bluetooth: mgmt: hold reference for hci_conn in mgmt_pending_cmds Dereferencing RCU-protected pointers outside critical sections is invalid and may lead to UAF. Use of hci_conn in hci_sync callbacks also needs to hold refcount to avoid UAF. Take appropriate locks for hci_conn lookups, and take refcount for hci_conn pointers stored in mgmt_pending_cmd so that the pointer stays valid. When accessing conn->state, ensure hdev->lock is held to avoid data race.
