Beware Android users! This critical bug can allow hackers to access your device: Here is how you can stay safe

India’s cybersecurity agency CERT-In has recently issued a high-severity warning for millions of Android users across the country. They warned the users about a newly found security flaw that affects devices running on older Android versions. The hackers can remotely run harmful code on vulnerable devices without needing user permission or interaction and can get access to your device. Once connected, the hacker can access your sensitive data, like messages, photos, social media and more. Moreover, he can also manipulate the device or the data. Here’s everything you need to know about the flaw and how you can be safe.

What is the Android security flaw?

The vulnerability has been identified as CIVN-2026-0219. It reportedly exists inside the Android Debug Bridge daemon, or ‘adbd’, a system component mainly used by developers for communication between Android devices and computers.

CERT-In says improper authentication handling inside this component has created a loophole that attackers can exploit. If a hacker is connected to the same network as the target device, they may be able to remotely execute malicious code without requiring additional permissions or any action from the user.

Which Android versions are affected?

The government advisory says that the devices running on the following Android versions are vulnerable:

• Android 14
• Android 15
• Android 16
• Android 16-QPR2

The warning applies to smartphones, tablets, smartwatches and other devices running affected Android versions.

Why this CERT-In warning matters

Cybersecurity experts consider remote code execution flaws among the most serious threats because they can allow attackers to gain control over parts of a device from a distance.

According to CERT-In, successful exploitation of this flaw may allow hackers to:

• Access sensitive information
• Manipulate files or system settings
• Compromise device security remotely
• Affect connected organisational networks
• Since Android powers billions of devices globally, vulnerabilities affecting recent Android versions can potentially impact a large number of users.

Google has released a security patch.

Google Android Security Bulletin has already published patch details related to the vulnerability in its May 2026 Android Security Bulletin.

Smartphone brands including Samsung, Vivo, OnePlus and others are expected to gradually roll out security updates for eligible devices. It is recommended that users update their systems as soon as possible.

How to stay safe

If you want to stay safe against the flaw, then all you need to do is follow the below-mentioned:

• Update your Android device regularly.
• Make sure that you don’t connect to unsecure Wi-Fi or hotspots.
• Avoid downloading apps from the black market or any online website that is not trusted.
• Do not open links or files sent to you via unknown people.
• Restart and update your devices regularly to ensure that the security patches are applied to your device.
