Kernel Version 4.14.117 Android Jun 2026

When building a custom kernel, developers do not rewrite code from scratch. Instead, they take the device's original source code provided by the manufacturer (e.g., Xiaomi, OnePlus, or Samsung) and "merge" upstream changes from the official Linux kernel repository.

specifically entered the Android ecosystem during the latter half of 2019, as a cumulative stable update that addressed several memory leaks, race conditions, and potential exploits discovered in earlier 4.14.x releases.

The Linux kernel serves as the core foundation of the Android operating system. It acts as the software bridge between your device's physical hardware and the Android Open Source Project (AOSP) framework. Among the various Long-Term Support (LTS) kernels deployed by Google and device manufacturers, represents a critical milestone in stability, security patching, and hardware support for millions of mid-generation Android devices. The Role of Linux Kernel 4.14 in Android

The Binder driver is the core of Android's Inter-Process Communication (IPC). Vulnerabilities in the Binder driver frequently allow for local privilege escalation (LPE). Version 4.14.117 includes critical upstream patches to prevent memory leaks and use-after-free vulnerabilities within the Android Binder framework.

Kernel version 4.14.117 represents a crucial milestone in Android's kernel history. It served as a stable, reliable launch kernel for Android 9, 10, and 11 devices, powering popular models like the Realme X2 and various car head units. However, its age makes it vulnerable to known CVEs. For users still on devices with this kernel, keeping the system up-to-date with the latest vendor security patches is paramount to mitigating these risks. For the broader Android ecosystem, the shift to GKI and newer LTS kernels (5.10, 5.15, and beyond) underscores the continuous evolution of the platform toward more modular, secure, and maintainable kernel architecture.

For the enthusiast community, the kernel version can be a point of discussion. In the world of custom ROMs like Resurrection Remix, developers sometimes have to weigh the benefits of updating to the "latest stable 4.14 kernel" against the stability of staying with a known working version like 4.14.117 . Changing the kernel can sometimes "break some feature" if not properly integrated, as a ROM is often closely tied to a kernel with custom patches.

Introduced in Android 8.0 and solidified in Android 9 (Pie) and 10, Project Treble modularized the Android OS framework to separate it from vendor-specific code. Kernel 4.14 was built from the ground up to support the Vendor Test Suite (VTS) and structural requirements of Treble, making it easier for manufacturers to update the Android system without rewriting the underlying kernel. 3. What Makes Version 4.14.117 Specific? When building a custom kernel, developers do not

This specific kernel version (4.14.117) was widely used in flagship and mid-range devices released or updated around 2019-2020: Samsung Galaxy S10 Go to product viewer dialog for this item. : Running Android 10.

This highlights the primary purpose of kernel updates: patching security vulnerabilities. Many of the security bulletins Google releases contain fixes for flaws found deep within the Linux kernel itself. By updating to a kernel version like 4.14.117 , which includes 75 patches, manufacturers could close security holes and protect users from potential exploits.

While kernel version 4.14.117 may seem like a minor footnote in the vast history of the Linux kernel, it represents the exact type of incremental maintenance that keeps the Android ecosystem secure and reliable. By sealing critical security loopholes and streamlining low-level hardware communication, this point release ensured that devices running Android 9 and 10 remained fast, safe, and stable throughout their lifecycles.

For security researchers and developers, the kernel source for certain devices (like the Realme 7 Pro) is available on GitHub, aiding in vulnerability analysis and custom kernel development. The Linux kernel serves as the core foundation

Devices powered by processors like the Snapdragon 845 or Snapdragon 660 often reached the end of their official manufacturer support cycles while running a 4.14-based kernel. For developers building modern Android 12, 13, or 14 custom ROMs for these legacy phones, pulling stable upstream patches like 4.14.117 is mandatory. It ensures that an old device remains secure against modern exploits even if the original manufacturer abandoned it years ago. Unlocking the "Mainline" Effort

This kernel version features enhanced support for cgroups v2. In Android, cgroups are essential for resource management, ensuring that foreground apps get priority memory and CPU allocation while background apps are throttled to save resources.
