The software uses a reference count to manage a resource, but it does not update or incorrectly updates the reference count.
Extended Description
Reference counts can be used when tracking how many objects contain a reference to a particular resource, such as in memory management or garbage collection. When the reference count reaches zero, the resource can be de-allocated or reused because there are no more objects that use it. If the reference count accidentally reaches zero, then the resource might be released too soon, even though it is still in use. If all objects no longer use the resource, but the reference count is not zero, then the resource might not ever be released.
chain/composite: use of incorrect data type for a
reference counter allows an overflow of the counter, leading to a free of
memory that is still in use.
Race condition causes reference counter to be
decremented prematurely, leading to the destruction of still-active object
and an invalid pointer dereference.
