Descriptions
In the Linux kernel, the following vulnerability has been resolved:
net: bridge: mst: fix suspicious rcu usage in br_mst_set_state
I converted br_mst_set_state to RCU to avoid a vlan use-after-free
but forgot to change the vlan group dereference helper. Switch to vlan
group RCU deref helper to fix the suspicious rcu usage warning.
