En el kernel de Linux, se resolvió la siguiente vulnerabilidad: netfilter: nft_chain_filter: maneja NETDEV_UNREGISTER para la cadena base inet/ingress Elimine netdevice de la cadena base inet/ingress en caso de que se informe el evento NETDEV_UNREGISTER; de lo contrario, permanecerá una referencia obsoleta a netdevice en la lista de enlaces.
A vulnerability was found in the Linux kernel's netfilter subsystem, related to the nft_chain_filter feature. This issue occurs when a NETDEV_UNREGISTER event is reported, which can leave a stale reference to a network device in the ingress basechain. If this issue is not addressed, this stale reference could result in lingering issues with network device handling.
