Null Pointer Dereference

Null Test After Dereference

Unchecked Parameter Dereference

Compass/ROSE

Can detect violations of this rule. In particular, ROSE ensures that any pointer returned by malloc(), calloc(), or realloc() is first checked for NULL before being used (otherwise, it is free()-ed). ROSE does not handle cases where an allocation is assigned to an lvalue that is not a variable (such as a struct member or C++ function call returning a reference)

CHECKED_RETURN

NULL_RETURNS

REVERSE_INULL

FORWARD_NULL

Finds instances where a pointer is checked against NULL and then later dereferenced

Identifies functions that can return a null pointer but are not checked

Identifies code that dereferences a pointer and then checks the pointer against NULL

Can find the instances where NULL is explicitly dereferenced or a pointer is checked against NULL but then dereferenced anyway. Coverity Prevent cannot discover all violations of this rule, so further verification is necessary
