  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nbatman-adv: clean untagged VLAN on netdev registration failure\n\nWhen an mesh interface is registered, it creates an untagged struct\nbatadv_meshif_vlan on top of it via the NETDEV_REGISTER notifier. But in\nthis process, another receiver of this notification can veto the\nregistration. The netdev registration will be aborted because of this veto.\n\nThe register_netdevice() call will try to clean up the net_device using\nunregister_netdevice_queue() - which only uses the .priv_destructor to\nfree private resources. In this situation, .dellink will not be called.\n\nThe cleanup of the untagged batadv_meshif_vlan must thefore be done in the\ndestructor to avoid a leak of this object.",
