Understanding and Resolving the “Kernel Security Check Failure” BSOD During Battlefield 6 Open Beta: A Technical Guide
Introduction
Blue Screen of Death (BSOD) errors can be particularly frustrating, especially when they hinder access to upcoming game releases like Battlefield 6 (BF6) Open Beta. A common BSOD encountered by players today is the “Kernel Security Check Failure,” which occurs immediately upon attempting to launch the game, preventing gameplay from even starting. This article offers a detailed analysis of this specific issue, explores potential causes, shares troubleshooting steps taken so far, and provides recommendations to mitigate or resolve the problem—helping gamers prepare for the full game release in October.
Understanding the Error: Kernel Security Check Failure
The BSOD in question is characterized by the Stop Code “KERNEL_SECURITY_CHECK_FAILURE” with a bug check code of 0x00000139. Specifically:
- Bug Check Code: 0x00000139
- Parameters:
- Parameter 1: 00000000`00000002
- Parameter 2: fffffe88`2e8eecf0
- Parameter 3: fffffe88`2e8eec48
- Parameter 4: 00000000`00000000
This error often indicates a security violation involving system memory or driver integrity, frequently linked to driver conflicts or system corruption.
Key Findings from System Analysis
The analysis identified that the crash was caused by the core Windows kernel driver “ntoskrnl.exe,” a critical component of the Windows operating system responsible for various system functions including memory management and hardware abstraction.
- Fault Location: ntoskrnl.exe+4fec10
- Stack Address: ntoskrnl.exe+3ab8d8
The presence of a stack cookie instrumentation violation suggests potential memory-related issues, possibly involving driver conflicts or system integrity problems.
Troubleshooting Attempts and Observations
A comprehensive set of troubleshooting steps was undertaken, including:
- Running game launchers (Steam and EA) with administrative privileges
- Forcing specific game-related processes (bf6event.exe and EAAntiCheat.GameServiceLauncher.exe) to run as Admin
- Ensuring all Windows updates, including optional ones, are installed
- Updating BIOS settings and firmware, with Secure Boot enabled
- Updating system drivers, particularly CPU and GPU drivers
- Enabling Memory Integrity (Core Isolation) to
