Thus, hcon set as NULL passes through to sco_conn_add(), which\ntries to get hcon->hdev, resulting in dereferencing a NULL pointer as\nreported by syzkaller.\n\nThe same issue exists for iso_connect_cis() calling hci_connect_cis().\n\nThus, make hci_connect_sco() and hci_connect_cis() return ERR_PTR\ninstead of NULL."}],"metrics":{},"references":[{"url":"https://git.kernel.org/stable/c/357ab53c83a5322437fa434e9a9e3e0bafe6b383","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67"},{"url":"https://git.kernel.org/stable/c/b4066eb04bb67e7ff66e5aaab0db4a753f37eaad","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67"}]}}]}
