FreeBSD -- Remote denial of service via null pointer dereference

Problem Description:

On a system exposing an NVMe/TCP target, a remote client can trigger a kernel panic by sending a CONNECT command for an I/O queue with a bogus or stale CNTLID.

Impact:

An attacker with network access to the NVMe/TCP target can trigger an unauthenticated Denial of Service condition on the affected machine.
