Xiaomi-C200-Firmware-Analysis

The Scope In this repo i will show how i got access to the UART interface even without the common set of exposed pins / test pads, using U-Boot and tricks to gain root on an early stage and eventually dumping the firmware Initial Reconnaissance There are a few key things clear from the PCB Chip...

CVE-2026-50720

The Ingenic T31 SoC boot ROM flash-boot verification path compares only a single 32-bit word of the RSA signature output against a single 32-bit word of the SHA-256 payload digest, rather than compare the full data. This allows an attacker with physical write access to boot media to forge modifie...

CVE-2026-50720

CVE-2026-50720 affects the Ingenic T31 SoC boot ROM flash-boot verification path. The root cause is a partial signature comparison : only a single 32-bit word of the RSA signature output is checked against a single 32-bit word of the SHA-256 payload digest, rather than the full digest. An attacke...
