AT&T is now pushing an update to both the HTC One M8 as well as the One M9 that contains a patch for the Stagefright exploit. The update, which weighs in anywhere from 28MB to 55MB, is likely to address only the security issues, and nothing else.

The updates are pushing out now, but may take a day or two to appear on your phone. If you want to check manually, you can head into your phone's Settings and check for the update. Let us know in the comments below if you have already received the update from AT&T.
