Vulnerability Details CVE-2023-53374
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: hci_conn: fail SCO/ISO via hci_conn_failed if ACL gone early
Not calling hci_(dis)connect_cfm before deleting conn referred to by a
socket generally results to use-after-free.
When cleaning up SCO connections when the parent ACL is deleted too
early, use hci_conn_failed to do the connection cleanup properly.
We also need to clean up ISO connections in a similar situation when
connecting has started but LE Create CIS is not yet sent, so do it too
here.
