FINAL RESULTS:

data/pg-stat-kcache-2.1.3/pg_stat_kcache.c:523:13:  [2] (integer) atoi:
  Unless checked, the resulting number can exceed the expected range
  (CWE-190). If source untrusted, check both minimum and maximum, even if the
  input had no minus sign (large numbers can roll over into negative number;
  consider saving to an unsigned value if that is intended).
	pgsk_max = atoi(pgss_max);
