⚠️ Risk & Real-World Impact
Worst Case
Camera functionality becomes completely unavailable, potentially affecting applications that depend on camera access.
Likely Case
Intermittent camera crashes or freezes during concurrent access scenarios.
If Mitigated
Minimal impact with proper thread synchronization and access controls in place.
🎯 Exploit Status
Exploitation requires precise timing and multi-threaded access to camera resources.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check Huawei security bulletins for specific fixed versions
