CVE-2026-68391
Description
AI Translation Available
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.
