To find IPC security vulnerabilities in OpenHarmony C++ system services, audit MessageParcel deserialization paths to verify read integrity, bounds checking, and logical validation against untrusted inputs.

Thread safety validation for OpenHarmony C++ shared state detects container thread-safety issues, iterator invalidation, deadlock risks, and TOCTOU patterns by enforcing consistent locking mechanisms.

Prevent PII and pointer leakage in OpenHarmony C++ logs by enforcing strict redaction of sensitive data and memory addresses before outputting any diagnostic logging information.

Yes, you can audit an xxxService.cpp and its corresponding xxxStub.cpp pair to systematically identify IPC input handling issues, concurrency hazards, sensitive logging, and strict permission validation checks.

The best way to validate caller permissions for privileged OpenHarmony operations is to systematically flag and enforce strict permission checks across all code paths handling untrusted IPC or network inputs.
