The analyzer has detected a potential error: memory is allocated and released through incompatible methods. For example, the analyzer will warn you if memory is allocated through the 'new' operator and released through the 'free' function.
Consider an example of incorrect code:
int *p = (int *)malloc(sizeof(int) * N); ... ... delete  p;
This is the fixed code:
int *p = (int *)malloc(sizeof(int) * N); ... ... free(p);
