Kernel Version — 4.14.117 Android

Fixes to use-after-free (UAF) bugs within the binder IPC (Inter-Process Communication) mechanism—the core communication highway of the Android OS.

Google mandates specific kernel versions for Android releases to ensure security and hardware compatibility. The 4.14 kernel branch became prominent during the eras of Android 9 (Pie) and Android 10. Why Kernel 4.14 Mattered

Outside, a drone delivery copter hummed past her window. Its navigation lights blinked in a slow, deliberate rhythm. Not a patrol , the kernel typed. A hunter. They are already here. They are in the light. Make your choice.

You’ll see something like:

For the technically curious, here is a snapshot of the impact that the Android common kernel version 4.14 had in just its first few months of development, compared to a mainline Linux kernel:

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.
