Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> r8169: fix LED-related deadlock on module removal<br /> <br /> Binding devm_led_classdev_register() to the netdev is problematic<br /> because on module removal we get a RTNL-related deadlock. Fix this<br /> by avoiding the device-managed LED functions.<br /> <br /> Note: We can safely call led_classdev_unregister() for a LED even<br /> if registering it failed, because led_classdev_unregister() detects<br /> this and is a no-op in this case.
