Weakness (CWE)

CWE-824: Access of Uninitialized Pointer

Base Incomplete

The product accesses or uses a pointer that has not been initialized.

More detail

If an attacker can influence the portion of uninitialized memory that is contained in the pointer, this weakness could be leveraged to execute code or perform other attacks.

Depending on memory layout, associated memory management behaviors, and product operation, the attacker might be able to influence the contents of the uninitialized pointer, thus gaining more fine-grained control of the memory location to be accessed.
