Upgrade Oracle:9 kernel to version 0:5.14.0-427.13.1.el9_4 or higher.
This issue was patched in ELSA-2024-2394.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel package and not the kernel package as distributed by Oracle. See How to fix? for Oracle:9 relevant fixed versions and status.

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.
