It is due to a race condition between learning still happening and a port being deleted, after all its fdbs have been flushed. The port&#39;s state has been toggled to disabled so no learning should happen at that time, but if we have MST enabled, it will bypass the port&#39;s state, that together with VLAN filtering disabled can lead to fdb learning at a time when it shouldn&#39;t happen while the port is being deleted. VLAN filtering must be disabled because we flush the port VLANs when it&#39;s being deleted which will stop learning. This fix adds a check for the port&#39;s vlan group which is initialized to NULL when the port is getting deleted, that avoids the port state bypass. When MST is enabled there would be a minimal new overhead in the fast-path because the port&#39;s vlan group pointer is cache-hot.</p> <p>[1] https://syzkaller.appspot.com/bug?extid=dd280197f0f7ab3917be</p> <p>In the Linux kernel, the following vulnerability has been resolved:</p> <p>net: bridge: fix use-after-free due to MST port state bypass</p> <p>syzbot reported[1] a use-after-free when deleting an expired fdb.
