Description

hci_conn_cleanup in net/bluetooth/hci_conn.c in the Linux kernel through 6.2.9 has a use-after-free (observed in hci_conn_hash_flush) because of calls to hci_dev_put and hci_conn_put. There is a double free that may lead to privilege escalation. A double-free vulnerability was found in the hci_conn_cleanup in net/bluetooth/hci_conn.c in the Linux Kernel. This issue may cause a denial of service or privilege escalation.
