I've had a panic which looks similar to that:

    panic: kernel diagnostic assertion "cred != NULL" failed: file ...
        kern/kern_auth.c, line 300
    cpu3: Begin traceback...
    kern_assert ... at netbsd:kern_assert+0x23
    kauth_cred_geteuid ... at netbsd:kauth_cred_geteuid+0x43
    sysctl_net_inet_tcp_ident ... at netbsd:sysctl_net_inet_tcp_ident+0x2fd
    sysctl_dispatch ... at netbsd:sysctl_dispatch+0xc7
    sys___sysctl ... at netbsd:sys___sysctl+0xea
    syscall ... at netbsd:syscall+0xaa

More details are in PR #48098.
