- Summary
- Bluetooth: hci_conn: fix potential UAF in set_cig_params_sync
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: hci_conn: fix potential UAF in set_cig_params_sync
hci_conn lookup and field access must be covered by hdev lock in set_cig_params_sync, otherwise it's possible it is freed concurrently.
Take hdev lock to prevent hci_conn from being deleted or modified concurrently. Just RCU lock is not suitable here, as we also want to avoid "tearing" in the configuration.
