What is CVE-2016-10225?

The sunxi-debug driver included in the Allwinner 3.4 legacy kernel allows unauthorized local users to escalate their privileges to root by sending a specific command to the '/proc/sunxi_debug/sunxi_debug' interface. This vulnerability poses significant security risks, enabling malicious users to execute arbitrary commands with elevated privileges, thereby compromising system integrity.

Exploit Proof of Concept (PoC)

PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
