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.
