CVE-2023-53374

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> Bluetooth: hci_conn: fail SCO/ISO via hci_conn_failed if ACL gone early<br /> <br /> Not calling hci_(dis)connect_cfm before deleting conn referred to by a<br /> socket generally results to use-after-free.<br /> <br /> When cleaning up SCO connections when the parent ACL is deleted too<br /> early, use hci_conn_failed to do the connection cleanup properly.<br /> <br /> We also need to clean up ISO connections in a similar situation when<br /> connecting has started but LE Create CIS is not yet sent, so do it too<br /> here.
