CVE-2022-49474

CVE-2022-49474 (Linux kernel) affects the Bluetooth SCO path. The issue arises when connecting the same SCO socket twice (sco_sock_connect), which can create two sco_conn objects but only one is bound to the socket. If the socket closes before the SCO connection is established, the timer for the ...
