Android phones at risk from ‘SMS of Death’; security warning issued for users

A new security vulnerability has emerged, causing concern for Android smartphone users. A specially crafted, malicious text message—dubbed the "SMS of Death"—can crash a phone’s system and render it inoperable, all without any user intervention.

According to security researcher Mark Blaszczyk, cybercriminals can exploit this flaw in Android devices to compromise a phone without requiring the user to click on a link or even open the message.

The dangerous message does not even appear in the inbox

A particularly alarming aspect of this security flaw is that the malicious message neither appears in the user's inbox nor triggers any notification. Despite this, it can disrupt the system responsible for managing phone calls.

Experts state that this vulnerability can cause active phone calls to be abruptly disconnected. There is even a risk that calls made to emergency services could be affected.

Multiple phones, including Google Pixel and Samsung Galaxy, are affected

Reports indicate that approximately 20 such malicious messages have been identified that can render an Android phone inoperable. This security vulnerability has been detected in various Android devices, including the Google Pixel and Samsung Galaxy.

The issue is linked to code present since Android 12. Researchers have designated this security flaw as CVE-2026-58882 and classified it as extremely serious.

What precautions should users take?

Experts have advised Android users to immediately install the latest security updates available for their smartphones. Older phones that have not been updated for a long time may remain vulnerable to these risks.

Users should regularly check for software updates on their phones to obtain the available fixes designed to protect against security vulnerabilities.
