SonicWall SonicOS Web Management Interface Stack Buffer Overflow threat

I had some guests who used my wifi. I continually get alerts that a threat is hitting both my rokus.

I phoned my wifi carrier and the tech said she'd have to advance my request to a technician and gave me a ticket #. He called back and it sounded like he was researching this threat. (I don't have this threat attacking any other wifi-enabled devices -- only roku).

He said to contact roku as it's something related to their device as it doesn't affect others. (My wifi has been blocking this; but it's increasing at attempts).

Just finished a chat with Shree on roku. She said to contact wifi carrier (why does everyone point the finger at someone else?) I was surprised I couldn't find this threat via a search.

Anyone else? If so, what did you do?

Thanks much!

Can't seem to post a pic here of the detailed message.
