Is iOS 26 a legitimate Apple update for iPhone 12 mini?

Possible Fake or Malicious “iOS 26” Update Showing on iPhone 12 mini

I’m reaching out because my iPhone 12 mini is showing an unusual software update option labeled “Upgrade to iOS 26.”

I understand that the latest official iOS version for my device should be iOS 18.7.1, so I’m concerned that this might be a bug or a spoofed update.

Could you please confirm whether this is a legitimate Apple update?

If not, I’d appreciate guidance on how to remove any potentially malicious configuration profiles or correct the issue.
