TL;DR
  • A newly disclosed Android vulnerability allows malicious text messages to silently crash a phone’s calling service, potentially interrupting emergency calls.
  • Repeated messages can trigger persistent crashes and reboot loops, making affected devices hard to recover without technical help.
  • Google developed a fix months before the public disclosure, but questions remain about when users will receive the patch.

Imagine dialing 911, only for your phone to suddenly drop the call. You haven’t pressed anything, your signal hasn’t disappeared, and there’s no obvious explanation. Somewhere in the background, however, a text message you never received has just brought your phone’s calling service to its knees.

That’s the frightening scenario behind SMS of Death, a newly disclosed Android vulnerability that lets attackers remotely disrupt phones without the victim lifting a finger.
