Kernel version 4.14.117 Android

Here’s a complete, ready-to-post summary about the Android kernel version 4.14.117 you can use on forums, blogs, or issue trackers.

2. Key Security Hardening Backports

Android’s security team frequently backports fixes from newer kernels into older LTS versions. Kernel 4.14.117 incorporated crucial hardening patches, including:

• CVE-2019-11815 (a race condition in the Linux kernel’s RDS protocol)
• CVE-2019-5489 (a mincore() information leak)
• Mitigations for Spectre V4 (speculative store bypass) on ARM64.

For Android users, this meant that devices running 4.14.117 were protected against a wave of speculative execution attacks that plagued earlier kernels.

Known remaining risks (version .117):

• CVE-2019-13272 – ptrace privilege escalation (fixed in .118+).
  Impact: Local root on some configurations.
• CVE-2019-11884 – Bluetooth L2CAP (fixed in .120+).
  Impact: Remote DoS or potential RCE.

✅ Recommendation: If deploying a new build, upgrade to 4.14.336+ (final LTS) or backport critical post-.117 patches.

1. The Lineage and Identity

To understand 4.14.117, we must deconstruct its versioning hierarchy: kernel version 4.14.117 android

• Base Version (4.14): This is an LTS (Long Term Support) kernel branch. It was officially designated as "Super LTS," meaning it was maintained for six years (until Jan 2024). It was a critical baseline for Android devices launching roughly between late 2017 and 2019.
• Patch Level (.117): This indicates the 117th incremental update to the 4.14 branch.
  • Release Timing: Kernel 4.14.117 was released in May 2019.
  • Context: This was a pivotal time for Android. Android 10 (Q) was in developer preview, and Android 9 (Pie) was the stable standard.

5. The Role in GKI (Generic Kernel Image)

Kernel 4.14 was the first branch designated for the Generic Kernel Image (GKI) initiative, which aimed to decouple the kernel from the hardware vendor implementation.

• In the pre-GKI era, SoC vendors (Qualcomm, MediaTek) would fork the kernel and heavily modify it, making updates impossible without vendor help.
• Kernel 4.14.117 was the target version for devices launching with Android 10, aiming to ship a "Generic" kernel binary where hardware drivers were loaded as modules rather than compiled into the core kernel. This specific version allowed Google to enforce ABI (Application Binary Interface) stability, meaning a driver compiled for 4.14.117 should work on any 4.14.117 GKI kernel.

Notable Devices Confirmed with 4.14.117

| Manufacturer | Device Model | Android Version (at kernel release) | |--------------|--------------|--------------------------------------| | Samsung | Galaxy A50, A20e, M30s | Android 9 Pie / Android 10 | | Xiaomi | Redmi Note 8, Mi A3 | Android 9 Pie | | Nokia | Nokia 4.2, Nokia 3.2 | Android 9 Pie | | Motorola | Moto G7 Play, Moto E6 | Android 9 Pie | | Google Pixel | Pixel 3a / 3a XL (early updates) | Android 10 | | OnePlus | OnePlus Nord N100 | Android 10 |

Additionally, many custom ROM communities (LineageOS, /e/ OS, crDroid) adopted 4.14.117 as a baseline for their builds targeting Snapdragon 660, 665, and 710 platforms.

Kernel 4.14.117 belongs to the 4.14 series, which Google utilized as a Common Kernel (ACK) Android 9, 10, and 11 LTS Foundation

: It is a "sublevel" release, meaning it contains stable bug fixes and security patches on top of the original 4.14 code. Device Lifecycle

: Devices shipping with this kernel were supported by Google through January 2024, following a 6-year LTS commitment. Key Technical Features

While 4.14.117 specifically focuses on stability, the 4.14 series introduced several major enhancements used by Android OEMs: Memory Efficiency CVE-2019-11815 (a race condition in the Linux kernel’s

: Support for Heterogeneous Memory Management (HMM), crucial for modern GPUs to share memory with the CPU. Security Hardening

: Implementation of KASLR (Kernel Address Space Layout Randomization) and hardened usercopy to protect against memory exploits. Performance : Introduction of the zstd compression algorithm

for filesystems like Btrfs and Squashfs, which helps speed up data access on mobile storage. Resource Management

: New "thread mode" for control groups (cgroups), allowing more granular resource distribution across process threads. Android Open Source Project Security & Maintenance
