CVE-2023-54038
A flaw was found in the Linux kernel's Bluetooth Host Controller Interface HCI connection handling. A local user could exploit this vulnerability when the hciconnectsco function returns a NULL pointer instead of an error pointer when no link is present. This improper handling of exceptional...

CVE-2023-54038
The CVE-2023-54038 issue affects the Linux kernel Bluetooth HCI path. The root cause is that hci_connect_sco() (and similarly hci_connect_cis()) returned NULL on error, causing sco_conn_add() to dereference hcon->hdev and crash. The fix switches to returning an ERR_PTR on error for both hci_co...
