No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

In some cases, the tcp-setmss handler may free the packet data and throw an error without halting the rule processing engine. A subsequent rule can then allow the traffic after the packet data is gone, resulting in a NULL pointer dereference.

Maliciously crafted packets sent from a remote host may result in a Denial of Service (DoS) if the tcp-setmss directive is used and a subsequent rule would allow the traffic to pass.
