{"id":"DEBIAN-CVE-2024-26801","details":"In the Linux kernel, the following vulnerability has been resolved:  Bluetooth: Avoid potential use-after-free in hci_error_reset  While handling the HCI_EV_HARDWARE_ERROR event, if the underlying BT controller is not responding, the GPIO reset mechanism would free the hci_dev and lead to a use-after-free in hci_error_reset.
