Emergency security update for Android: 124 vulnerabilities fixed – how to check?

The June Android security update was one of the biggest this year. Google has fixed 124 critical vulnerabilities that compromised user privacy. One of the main reasons for the urgent update was a flaw that attackers are already actively exploiting in real conditions.

Dangerous vulnerability numbered CVE-2025-48595

The central problem of the June update was a vulnerability with the identifier CVE-2025-48595. It affects the core Android framework and allows hackers to gain elevated privileges on the system without any interaction from the device owner. According to official data, this loophole has already been used for targeted attacks of a limited scope. Smartphones running Android 14, 15, 16 and Android 16 QPR2 are at risk.

Details and structure of security patches

In total, Google has closed 123 additional security holes in addition to the above-mentioned vulnerability. The deployment update process is divided into two stages:

• Patch dated June 1, 2026: closes the main components of the OS and eliminates 18 critical vulnerabilities.

To fully protect your smartphone, it is enough to install one of these patches.

Time frame for receiving updates

The speed of installing patches directly depends on the manufacturer of your smartphone. Google Pixels always remain a priority, while owners of flagship Samsung models usually receive protection after a few days. For users of budget devices and models older than two years, the update may take several weeks. It is recommended that you do not ignore system update notifications.

How to check the protection status yourself

To make sure your device is secure, go to Settings, select Security & Privacy, and then open System & Updates. Check the security level date: it must correspond to June 1 or June 5, 2026. If an older date is indicated, be sure to search for and install available updates.
