When deleting a vlan tunnel the tunnel_dst pointer is set to NULL without waiting a grace period (i.e. while it&#39;s still usable) and packets egressing are dereferencing it without checking. Use READ/WRITE_ONCE to annotate the lockless use of tunnel_id, use RCU for accessing tunnel_dst and make sure it is read only once and checked in the egress path. The dst is already properly RCU protected so we don&#39;t need to do anything fancy than to make sure tunnel_id and tunnel_dst are read only once and checked in the egress path.</p> <p>In the Linux kernel, the following vulnerability has been resolved:</p> <p>net: bridge: fix vlan tunnel dst null pointer dereference</p> <p>This patch fixes a tunnel_dst null pointer dereference due to lockless access in the tunnel egress path.
