Crash Summary

A crash occurred in the Windows system, indicated by a SYSTEM_SERVICE_EXCEPTION bugcheck. The crash was triggered by the starshieldfsflt.sys module, specifically at address fffff88000f01c7f. The crash is likely related to a concurrency issue or a memory access violation.

Detailed Analysis

The crash is a result of a SYSTEM_SERVICE_EXCEPTION bugcheck, which suggests an exception occurred while executing a system service routine. The exception code is 0xC0000005, which corresponds to an access violation. The faulting module is starshieldfsflt.sys, and the faulting instruction address is fffff88000f01c7f.

The stack trace shows that the crash occurred in the fltmgr!FltSendMessage function, which is part of the Filtering Manager. This function is likely sending a message to another part of the system. The stack then transitions to starshieldfsflt+105a, indicating that the crash is within the starshieldfsflt.sys module itself.

Stack Trace Analysis

The stack trace reveals the sequence of function calls leading up to the crash:

• nt!KeBugCheckEx: Reports the bug check.
• nt!KiBugCheckDispatch: Dispatches the bug check.
• nt!KiSystemServiceHandler: Handles system service requests.
• nt!RtlpExecuteHandlerForException: Executes the handler for the exception.
• nt!RtlDispatchException: Dispatches the exception.
• nt!KiDispatchException: Dispatches the exception for kernel-mode code.
• nt!KiPageFault: Handles page faults.
• fltmgr!FltSendMessage: The function in which the crash occurred.
• starshieldfsflt+105a: The specific address within the starshieldfsflt.sys module where the crash occurred.

Root Cause

The root cause of the crash appears to be an access violation within the starshieldfsflt.sys module. This could be due to a concurrency issue, such as improper locking or synchronization, or a memory access violation, such as a pointer being dereferenced incorrectly.

Recommendations

1. Analyze the code at starshieldfsflt+105a to identify the exact cause of the access violation.
2. Review the implementation of the fltmgr!FltSendMessage function for potential concurrency issues.
3. Check for any recent changes to the starshieldfsflt.sys module or related system components that might have caused this issue.
4. Consider updating the starshieldfsflt.sys module to the latest version, if available, as it might contain fixes for known issues.
