# CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.

Attack complexity: More severe for the least complex attacks.

Privileges required: More severe if no privileges are required.

User interaction: More severe when no user interaction is required.

Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.

Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.

Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.

Availability: More severe when the loss of impacted component availability is highest.

### Weaknesses

Weakness CWE-416

#### [Use After Free](/content/advisories?query=cwe%3A416/index.html)

The 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 Any operations using the original pointer are no longer valid because the memory belongs to the code that operates on the new pointer.
