Weakness (CWE)
CWE-908: Use of Uninitialized Resource
The product uses or accesses a resource that has not been initialized.
How to prevent it (4 mitigations)
-
Implementation
Explicitly initialize the resource before use. If this is performed through an API function or standard procedure, follow all required steps.
-
Implementation
Pay close attention to complex conditionals that affect initialization, since some branches might not perform the initialization.
-
Implementation
Avoid race conditions (CWE-362) during initialization routines.
-
Build and Compilation
Run or compile the product with settings that generate warnings about uninitialized variables or data.
