TIMELINE Sep 17 Reserved by Linux Sep 18 Published (CNA: Linux) Aug 4 RESCORED — CVE-2023-53374 (Linux). CVSS 8.8 → 7.8 (NVD).
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.
