In the fast-paced world of mobile technology, ensuring the security of our devices is paramount. Google, the company behind the Android operating system, has recently released its December Android security updates, fixing 85 vulnerabilities.

Let’s dive into the highlight of this release and understand why it is crucial to keep your Android systems updated.


Android Security Updates Address 85 Vulnerabilities


These December security updates address 85 vulnerabilities, one of which is a critical zero-click remote code execution bug discovered in Android’s System component. Dubbed CVE-2023-40088, this issue could lead to remote (proximal/adjacent) code execution with no additional execution privileges needed. User interaction is not required for exploitation.

It is still unknown if this vulnerability has been exploited in the wild. However, the potential for remote code execution without user interaction underscores the urgency of patching devices as soon as possible.


Other Critical Security Vulnerabilities


In addition to the zero-click RCE bug, Google fixed three critical vulnerabilities (CVE-2023-40077, CVE-2023-40076, and CVE-2023-45866) related to privilege escalation and information disclosure in the Android Framework and System components. A critical vulnerability in Qualcomm’s closed-source components was also patched.


Past Instances of Android Zero-Day Exploits


Google addressed two zero-day vulnerabilities (CVE-2023-4863 and CVE-2023-4211) in October. Another actively exploited zero-day (CVE-2023-35674) in the Android Framework component was fixed in September’s security updates. This flaw could enable attackers to elevate privileges without needing user interaction or additional execution privileges.

Like before, the December security updates are also rolled out in two sets: 2023-12-01 and 2023-12-05. The latter contains more fixes for third-party closed source and Kernel components in addition to all fixes from the first one. It is important to note that not all Android devices may require these additional patches.

Unlike Google Pixel smartphones, which get immediate security updates, other manufacturers may require additional time to release the patches. This is because comprehensive testing would be required to ensure compatibility with various hardware configurations.




In today’s digital world, staying up-to-date with Android security updates is essential. Users should prioritize the installation of these updates to safeguard their devices against potential exploits and ensure a seamless and secure Android experience.
