Samsung has just released one of the most important security updates of the year for its Galaxy line of mobile phones. This is not a minor or routine patch that fixes minor graphical errors, but an urgent fix designed to plug critical security holes that have recently been found in its operating system.
It is a Security Maintenance Release (SMR), and it fixes between 34 and 45 vulnerabilities—depending on the specific smartphone model—which, if not addressed soon, could allow third parties to gain complete remote control of your smartphone. If you have a Samsung, we strongly recommend that you update to the latest version immediately.
Samsung’s dangerous bugs
Unlike other updates, this November 2025 update does not introduce any new visual changes to the One UI interface. It focuses on the most serious bugs, classified as Remote Code Execution (RCE). An RCE flaw allows an attacker to inject and execute malicious code on your phone from a remote location. In other words, a hacker can take control of your device without even physically having it in their hands.
These critical flaws lie in their “Zero-Click” exploitation potential, where no action is required on the part of the user for the hacker to disable. With this type of hack, you can’t blame yourself; you don’t need to accidentally click on a malicious link or open a fraudulent attachment. All it takes is for your device to process a specially crafted data packet or file in the background for the exploit to run.
This ability to attack silently and invisibly is what makes these software system flaws so dangerous and urgent to fix. That’s why Samsung has rushed to release an update.
Vulnerabilities fixed
Unfortunately, the critical flaws identified by Google in the Android system affect a wide range of versions.
These vulnerabilities existed from Android 13 to Android 16. In addition to the operating system flaws, the update includes other specific fixes. Twenty-five other flaws from Google’s Android security bulletin have been fixed. Samsung has also added nine of its own security fixes that affect its One UI software layer.
In addition, the patch includes 11 specific fixes for Exynos processors, which affected models manufactured between 2019 and 2024, so coverage is very broad on Galaxy devices.
Detecting security flaws in an operating system is an ongoing process, often carried out by researchers who notify the company privately. Some of the specific bugs fixed in this version were already detected in September 2025. Samsung, like Google, operates on a standard monthly security patch cycle. Once the solution to these issues has been verified and developed, it is implemented in the nearest monthly update window. The update began promptly in key markets such as South Korea and Vietnam, two of the countries with the highest percentage of Samsung users. From there, the patch spread globally in a matter of days.
The risks of not updating
Although it can be a hassle to update your device—often the patch isn’t fully polished and you end up with errors on your phone—Galaxy owners who don’t update their device to the latest version are at high risk. The previous operating system was socially vulnerable to hacking.
There is a common principle in cybersecurity: when a patch is released, information about the vulnerability is made public. This is why attackers and cybercriminals immediately study the correction code to understand the original flaw. They then develop malware designed to exploit that error, targeting users who have not yet installed the update. This is how your phone becomes an easy target (in this case, an open backdoor). If they don’t attack you, they can exploit a vulnerability and gain complete control of your device. The consequences are serious and range from theft of sensitive data to espionage.
That’s why, if you have a Samsung smartphone or device, we strongly recommend that you take a few minutes to plug it in, connect it to a stable Wi-Fi network, and download the latest software update.
