Mi Firmware Pangu !exclusive! → [ DIRECT ]

The standard BROM verifies DA signature via RSA-2048. MFP sends a malformed SBC (Secure Boot Challenge) response that causes a stack overflow in the hash comparison routine, skipping signature validation.

In the Xiaomi ecosystem, specifically regarding the goodix_fingerprint or fpc_fingerprint subsystems, the term (often seen in kernel logs as pangu_drv or within binary blobs) represents the Trusted Execution Environment (TEE) driver layer . mi firmware pangu

In the Xiaomi kernel source (e.g., for devices like the Mi 9, Mi 10, Mi 11), look for directories such as: drivers/input/fingerprint/ or drivers/misc/goodix_fingerprint/ The standard BROM verifies DA signature via RSA-2048
