NVD Description
Note: Versions mentioned in the description apply only to the upstream kernel-debug-debuginfo package and not the kernel-debug-debuginfo package as distributed by Rocky-Linux.
See How to fix? for Rocky-Linux:8 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.
