Multiple industrial products are affected by a vulnerability in the kernel known as TCP SACK PANIC. The vulnerability could allow a remote attacker to cause a denial of service condition. OpenBSD kernel version <= 6.5 can be forced to create long chains of TCP SACK holes that causes very expensive calls to tcp_sack_option() for every incoming SACK packet which can lead to a denial of service.
