Description
In the Linux kernel, the following vulnerability has been resolved: Bluetooth: eir: Fix using strlen with hdev->{dev_name,short_name} Both dev_name and short_name are not guaranteed to be NULL terminated so this instead use strnlen and then attempt to determine if the resulting string needs to be truncated or not.
