Description
In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
Bluetooth: btrtl: check for NULL in btrtl_set_quirks()<br />
<br />
The btrtl_set_quirks() has accessed btrtl_dev->ic_info->lmp_subver since<br />
b8e482d02513. However, if installing a Realtek Bluetooth controller<br />
without the driver supported, it will hit the NULL point accessed.<br />
<br />
Add a check for NULL to avoid the Kernel Oops.
