The port number is checked and it just prints an error message but it still continues to use the invalid port. And as a result it accesses memory which is not its resulting in BUG report from KASAN.
Yes there is an issue with out of bounds access. But this isn't the right fix.

I sent in a fix for this last Friday.
And I can confirm this patch also fixes the issue tested with the reproducer I was using in my vm.
Great Thanks for testing the patch.
thanks, -- Shuah
