A NULL pointer dereference flaw was found in the Linux kernel’s Bluetooth HCI UART driver. This flaw allows a local user to crash the system.

Mitigation

To mitigate this issue, prevent module hci_uart from being loaded. Please see <https://access.redhat.com/solutions/41278&gt; for how to blacklist a kernel module to prevent it from loading automatically.
