data/edac-utils-0.18/src/lib/libedac.c:497:9: [4] (format) vsnprintf:
If format strings can be influenced by an attacker, they can be exploited,
and note that sprintf variations do not always \0-terminate (CWE-134). Use
a constant for the format specification.
n = vsnprintf (buf, sizeof (buf) - 1, format, ap);
