Weaknesses
CWE · root cause- CWE-264Permissions, Privileges, and Access ControlsWeaknesses in this category are related to the management of permissions, privileges, and other security features that are used to perform access control.
- CWE-416Use After FreeThe product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
Affected systems
Known conditions: local access, low-privilege account, user interaction (CVSS vector). Other conditions: not stated in public data.
