Protecting kernel memory from user-space exploitation.
Native support for the zstd compression algorithm in Btrfs and Squashfs file systems.
Fixes to use-after-free (UAF) bugs within the binder IPC (Inter-Process Communication) mechanism—the core communication highway of the Android OS.
kernel. This means it received years of security patches and bug fixes from the Linux community, making it a stable choice for manufacturers like Samsung and Xiaomi. Android Compatibility kernel version 4.14.117 android
The Android operating system relies entirely on the Linux kernel to manage hardware, memory, and core security. Among the various Long-Term Support (LTS) kernels deployed in mobile history, Linux kernel version 4.14.117 stands out as a critical milestone. It served as a baseline infrastructure upgrade for devices transitioning through Android 9 Pie, Android 10, and Android 11.
What or chipset (e.g., Snapdragon, MediaTek) are you targeting?
The 4.14.117 kernel was a pivotal release for memory hardening, serving as the foundation for features later standardized in Android 10. Protecting kernel memory from user-space exploitation
The 4.14.117 confirms the kernel base. The extra string ( -g12345678 ) indicates a specific vendor build hash.
This specific version is significant because it was the mandated "GKI" (Generic Kernel Image) seed for early Android 10 launches and contains critical security infrastructures, such as the initial hardening of memory allocators and hardware-backed security hooks.

The ".117" patch level indicates that specific security vulnerabilities were patched. Two critical classes of bugs were addressed in this specific incremental update:
If you are working on a specific development project using this kernel, tell me: What are you targeting?
The ".117" patch level indicates a maintenance release focused primarily on bug fixes and security vulnerability patches.
Android relies heavily on EAS to balance performance and battery life across ARM big.LITTLE or DynamIQ CPU layouts. Version 4.14.117 refined task placement, ensuring lightweight background tasks stayed on power-efficient cores while heavy workloads instantly woke up high-performance cores.
