This means that reparenting (happened when the device is actually freed) is delayed and, during that delay, parent controller device (hciX) may be deleted. Since the latter may create a dangling pointer to freed parent, avoid that scenario by reparenting to NULL explicitly. (CVE-2024-53237)

 - In the Linux kernel, the following vulnerability has been resolved: Bluetooth: iso: Always release hdev at the end of iso_listen_bis Since hci_get_route holds the device before returning, the hdev should be released with hci_dev_put at the end of iso_listen_bis even if the function returns with an error.
 (CVE-2024-57879)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the CentOS 9 Stream kernel package.
