Recommendation: Monitor — no exploitation signal at the moment.

In Meari IoT SDK image handling (libmrplayer.so) as observed in CloudEdge 5.5.0 (build 220), Arenti 1.8.1 (build 220), and related white-label apps (<= 1.8.x), baby monitor ".jpgx3" files use reversible XOR over only the first 1024 bytes with a predictable key derivation model.
