Google discovers serious security flaw on Samsung smartphone series

Google security experts have discovered a serious security vulnerability on a series of Samsung smartphones that hackers can exploit and gain unauthorized access to the device.

Specifically, security experts from Google's Threat Analysis team discovered a serious security vulnerability on some Exynos chips developed by Samsung itself.

This security vulnerability exists on several Samsung chip models including Exynos 9820, 9825, 850, 990 and W920. These are the types of chips used on both Samsung smartphones and smartwatches such as Galaxy S10, S20, Note 10/10+, A51 5G, A71, M13,…

The Exynos chip developed by Samsung has a dangerous security hole, allowing hackers to attack and penetrate smartphones and smartwatches.

Google ranked this security flaw as “very serious”. Xingyu Jin and Clement Lecigne, the two experts who discovered this security flaw, said that hackers can exploit it to infiltrate and execute malicious code on the device remotely to take control and steal user data.

Google immediately sent a warning to Samsung about the security hole found, and said that at the time the error was discovered, there was no sign that hackers had exploited this error to attack users.

Samsung also quickly released patches to fix the security holes discovered by Google. At the time Google and Samsung announced this security flaw, the patches had already begun to be released to users.

In essence, the vulnerability can be thought of as a busy office building. When a task is completed, the office door should be closed and cleaned up. However, this flaw is like the door is left wide open after everyone leaves, meaning the memory is not properly cleared after a process is finished, allowing hackers to gain access and control of the user's phone.

A Samsung spokesperson said it is committed to providing the highest level of security to its users, and advised users to update their devices with the latest patches.
