Security vulnerabilities and automated fixes for cli security issues

A critical buffer overflow vulnerability was discovered and patched in the linenoise.c input library used by the ds4 CLI tool, where unchecked memcpy operations could allow attackers to overwrite adjacent memory regions. The fix adds proper bounds checking before memory copy operations, preventing potential heap and stack corruption. This vulnerability serves as a timely reminder of why input validation and buffer size verification remain essential disciplines in C programming.
