Security vulnerabilities and automated fixes for arm issues

A critical stack buffer overflow vulnerability was discovered in the ARM Hardware Abstraction Layer (HAL) initialization code, where an unchecked `vsprintf()` call could allow an attacker to overwrite the stack frame and achieve arbitrary code execution at the kernel level (ring-0). The fix replaces `vsprintf()` with `vsnprintf()` — a single-character change with enormous security implications. Left unpatched, this vulnerability could have allowed malicious hardware enumeration data or boot-time
