The vulnerability of the hci_conn_getPhy function in the Linux operating system’s Bluetooth driver allows a hacker to cause a service failure.

The vulnerability of the hciconngetPhy function in the Linux operating system’s Bluetooth driver leads to a freeze. Exploiting this vulnerability can allow an attacker to cause service failures...

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.
