Your Android device’s security is more important than ever. This August 2025, Google released its latest security update addressing six critical vulnerabilities — including two severe flaws in Qualcomm chips that were already being actively exploited in targeted attacks.
At TecnetOne, we want you to understand the details of these vulnerabilities, why they pose a real risk, and what you must do to keep your device protected.
The two most severe vulnerabilities have been cataloged as CVE-2025-21479 and CVE-2025-27038, both reported through the Android Security Team in January of this year.
Both flaws open the door to highly sophisticated attacks, allowing attackers to manipulate device memory and execute potentially malicious code without your consent.
In June, Qualcomm warned of signs of active exploitation, according to Google’s Threat Analysis Group (TAG). At that time, the company released initial patches for device manufacturers (OEMs), strongly recommending immediate installation.
However, because many manufacturers are slow to adapt updates, millions of Android devices remained exposed until Google’s official patch.
On June 3, the U.S. CISA (Cybersecurity and Infrastructure Security Agency) added these vulnerabilities to its catalog of actively exploited flaws, requiring federal agencies to secure their devices no later than June 24.

In addition to the Qualcomm vulnerabilities, Google also fixed:
The patches were released in two update levels:
You might think these vulnerabilities are too technical or only affect large companies. But the truth is: any Android user could be at risk.
If your device uses a Qualcomm chip (as most mid- and high-end Android phones do), attackers could:
At TecnetOne, we often see that the most effective attacks exploit known vulnerabilities left unpatched.
If you own a Google Pixel device, you’ll likely receive these updates immediately. But many other manufacturers take longer to adapt patches to their hardware and software configurations.
That delay creates a vulnerability window that attackers exploit. That’s why it’s critical to:
This is not the first time Android has faced zero-day exploitation:
These examples prove these flaws are not theoretical — they are actively used for espionage, data theft, and device control.

As cybersecurity experts, we recommend these practical measures:
Go to Settings > System > Software Update and install the August 2025 patch.
Ensure your device shows the 2025-08-05 patch level for complete coverage.
Malware often disguises itself as legitimate apps. Always download from Google Play.
Mobile antivirus or EDR can detect suspicious behavior even when the system does not.
Even if your password is stolen, MFA makes unauthorized access much harder.
Subscribe to reliable security bulletins (like TecnetBlog) or trust partners such as TecnetOne for updates on critical vulnerabilities and mitigations.
The most worrying aspect is that these vulnerabilities were already being exploited in targeted attacks before Google’s patch. This proves cybercriminals are always one step ahead.
The only way to protect yourself is to act quickly: update your devices as soon as patches are available and rely on additional defenses to stop unknown threats.
At TecnetOne, we know your mobile devices are now at the center of your personal and professional life. Losing control over them is not an option.
The Qualcomm flaws in Android are further proof of how fragile security can be if timely measures are not taken. With the August 2025 update, you have the chance to close doors that attackers are already using.
