Описание

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: ISO: Fix not releasing hdev reference on iso_conn_big_sync hci_get_route() returns a reference-counted hci_dev pointer via hci_dev_hold(). The function exits normally or with an error without ever releasing it.

A flaw was found in the Linux kernel's Bluetooth subsystem. The hci_get_route() function, used in the ISO (Isochronous Stream) connection handling, fails to release a reference-counted hci_dev pointer. This resource leak could lead to a Denial of Service (DoS) condition.
