RH.LEAKResource leakThe RH.LEAK checker finds instances in which all descriptors related to a previously acquired, but unreleased, resource are lost. Vulnerability and riskThere are situations in which resources are limited, and if a resource isn't properly released, it will be unavailable at the next access attempt. Vulnerable code example
1 #include <stdio.h>
2 int foo (const char *name) {
3 FILE *f = fopen(name, "r");
4 //...//
5 if (some_error) return 1;
6 //...//
7 fclose(f);
8 return 0;
9 }
Klocwork flags the code at line 5, indicating that a resource may be lost. |
