📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Permanent device bricking requiring hardware replacement if the camera subsystem becomes permanently unstable.
Likely Case
Temporary device crash/reboot when camera functionality is accessed, disrupting device availability.
If Mitigated
No impact if patched or if camera hardware is disabled/not used.
🎯 Exploit Status
Requires kernel-level access or malicious app with camera permissions; not trivial but feasible for determined attackers.
