Summary
Fix critical severity security issue in
samples/metee_mkhi.c.Vulnerability
V-001samples/metee_mkhi.c:165Description: In samples/metee_mkhi.c at line 165, the function vsprintf() is used to format a string into the 'msg' buffer without any maximum length constraint. Unlike vsnprintf(), vsprintf() has no second parameter to limit output size. If the formatted output — determined by the format string 'fmt' and variadic arguments 'varl' — exceeds the allocated size of 'msg', the function will write beyond the buffer boundary into adjacent memory. This is a textbook unbounded write vulnerability (CWE-120/CWE-787) that has been exploited in practice for decades.
