CVE-2024-27021
What it is
In the Linux kernel, the following vulnerability has been resolved: r8169: fix LED-related deadlock on module removal Binding devm_led_classdev_register() to the netdev is problematic because on module removal we get a RTNL-related deadlock. Fix this by avoiding the device-managed LED functions. Note: We can safely call led_classdev_unregister() for a LED even if registering it failed, because led_classdev_unregister() detects this and is a no-op in this case.
