For developers and custom ROM enthusiasts, 4.14.117 is often viewed as a "mature" kernel. It is stable enough for daily use but modern enough to support features like
Point release 4.14.117 includes essential backports for security vulnerabilities (CVEs).
Linux kernel version is an older Long Term Support (LTS) version commonly found in Android 10 devices. While the 4.14 series officially reached End of Life (EOL) in January 2024 , Google provides extended maintenance for specific Android common kernels. 📱 Device Compatibility kernel version 4.14.117 android
Android 8.0 introduced Project Treble. Kernel 4.14 was the first major LTS version to fully support the Vendor NDK (VNDK) separation required by Treble. While Kernel 5.4 eventually introduced the full Generic Kernel Image (GKI) where the kernel is a standalone module, 4.14.117 was the workhorse of the "pre-GKI" Treble era. It allowed system partitions to be updated independently of the vendor partition, but the kernel itself remained tightly coupled to the vendor's hardware drivers.
Kernel 4.14.117 benefited directly from Project Treble's architectural split. By separating the core Android OS framework from the low-level vendor implementation, chipmakers could deliver stable 4.14.117 kernel branches to OEMs. This allowed older devices running kernel 4.4 or 4.9 to potentially upgrade to 4.14, extending the functional lifespan of millions of smartphones.

The ".117" patch level indicates that specific security vulnerabilities were patched. Two critical classes of bugs were addressed in this specific incremental update:

Android devices primarily utilize or f2fs (Flash-Friendly File System) for internal storage. This point release patched structural vulnerabilities in how the kernel handles dirty pages and file locking. By preventing file system corruption during sudden power losses (such as a phone dropping to 0% battery), 4.14.117 protected user data from corruption. 3. Advanced Power Management (EAS)

Security is the primary reason point releases like 4.14.117 are compiled. This version mitigated several high-profile vulnerabilities, including variants of the hardware execution flaws. It also introduced stricter bounds checking to prevent buffer overflow attacks within device drivers. Project Treble and Kernel 4.14 While Kernel 5
The 4.14.117 release was a stable point update focused on bug fixes, regression corrections, and hardening. It did not introduce sweeping new features—which is exactly what mobile stability requires. Instead, it delivered critical refinements across several subsystems: 1. Networking Stack and Wi-Fi Stability
