In the Linux kernel, the following vulnerability has been resolved:net: bridge: vlan: fix memory leak in __allowed_ingressWhen using per-vlan state, if vlan snooping and stats are disabled,untagged or priority-tagged ingress frame will go to check pvid state.If the port state is forwarding and the pvid state is notlearning/forwarding, untagged or priority-tagged frame will be droppedbut skb memory is not freed.Should free skb when __allowed_ingress returns false.
