CVE-2022-50447 is a null-pointer dereference in the Linux kernel Bluetooth hci_conn subsystem. Connecting multiple Bluetooth ISO sockets without using DEFER_SETUP can cause hci_create_cis_sync to dereference a NULL object while processing HCI command synchronization work. KASAN detected an invalid two-byte read at a low address during the affected execution path.
