Oracle Linux: CVE-2022-49136: ELSA-2025-10669: kernel security update (IMPORTANT)

In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: hci_sync: Fix queuing commands when HCI_UNREGISTER is set
hci_cmd_sync_queue shall return an error if HCI_UNREGISTER flag has
been set as that means hci_unregister_dev has been called so it will
likely cause a uaf after the timeout as the hdev will be freed.
A vulnerability was found in the Linux kernel's Bluetooth subsystem in the `hci_cmd_sync_queue()` function. There was a missing check for whether the `HCI_UNREGISTER` flag had been set, meaning that commands were still sent even as the Bluetooth device was being unregistered. This issue could lead to a use-after-free scenario where the command is executed after the device structure is freed, potentially leading to a crash, arbitrary code execution, and system instability.
