- EPSS: 1.2% probability of exploitation in the next 30 days
- Public exploit or detection template: none known

Description
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.
Affected products
- FreeBSD: 13.5, 13.5-p1, 13.5-p2, 13.5-p3, 13.5-p4, 13.5-p5 (+9)
