Kernel Version 4.14.117 Android [portable]

The transition to the 4.14 branch brought significant improvements over older 3.18 or 4.4 kernels, including better memory management and enhanced support for multi-core processors. What’s New in Revision 4.14.117?

In the sprawling ecosystem of Android devices—from budget-friendly handsets to rugged industrial IoT modules—the Linux kernel remains the foundational bridge between software and hardware. While end-users often obsess over Android OS version numbers (Android 10, 11, 12, etc.), developers and security professionals pay closer attention to the kernel version string. One specific identifier that appears across thousands of devices worldwide is . The transition to the 4

First, . Android’s security model is deeply tied to the kernel. Features like seccomp-bpf (which restricts system call access), SELinux (mandatory access control), and hardened memory allocators rely on kernel-level support. The 4.14 kernel brought important improvements from the upstream Linux world, including better mitigation for hardware vulnerabilities like Spectre and Meltdown (retrofitted via backports) and enhanced support for Virtual KMS (Kernel Mode Setting). For a device stuck on kernel 4.14, the .117 revision number indicates that while it may not have the absolute latest features (like those in 5.10 or 5.15), it has received a specific set of stable fixes. In the Android world, a kernel that is not updated beyond its LTS window becomes a "graveyard" of known, unpatched Common Vulnerabilities and Exposures (CVEs).

: A high-severity Use-After-Free (UaF) vulnerability ( CVE-2021-1940 ) was identified in the Qualcomm NPU driver on devices using this kernel, potentially allowing arbitrary code execution.
