A flaw was found in the Bluetooth Host Controller Interface (HCI) synchronization module (`hci_sync`) of the Linux kernel. A use-after-free (UAF) vulnerability exists in the `le_read_features_complete` function, where a freed `hci_conn` object is accessed. This can allow an attacker to cause a system crash, leading to a denial of service.
