CVE-2023-28903Public exploit

System reboot via EXIF integer overflow

Published Jun 28, 2025 · Updated Jun 30, 2025

Integer overflow in the picture handler of JOYNEXT MIB3 OI MQB 0304 and earlier allows attackers to reboot the system via a crafted JPEG. During EXIF parsing, tsd.media.picserver.mib3.app.target adds the 32-bit tag_data_size and tag_data_offset before validating their range, so the wrapped sum produces memory leaks or a segmentation fault. Physical access to insert a USB flash drive and user interaction to open the image are required; process termination causes the whole infotainment system to reboot, interrupting multimedia and navigation.
