A community-developed list of SW & HW weaknesses that can become vulnerabilities
CWE VIEW: Weaknesses in the 2023 CWE Top 25 Most Dangerous Software Weaknesses
 Objective Audience
RelationshipsThe following graph shows the tree-like relationships between
weaknesses that exist at different levels of abstraction. At the highest level, categories
and pillars exist to group weaknesses. Categories (which are not technically weaknesses) are
special CWE entries used to group weaknesses that share a common characteristic. Pillars are
weaknesses that are described in the most abstract fashion. Below these top-level entries
are weaknesses are varying levels of abstraction. Classes are still very abstract, typically
independent of any specific language or technology. Base level weaknesses are used to
present a more specific type of weakness. A variant is a weakness that is described at a
very low level of detail, typically limited to a specific language or technology. A chain is
a set of weaknesses that must be reachable consecutively in order to produce an exploitable
vulnerability. While a composite is a set of weaknesses that must all be present
simultaneously in order to produce an exploitable vulnerability.

1425 - Weaknesses in the 2023 CWE Top 25 Most Dangerous Software Weaknesses

Variant level weaknesses typically describe issues in terms of 3 to 5 of the following dimensions: behavior, property, technology, language, and resource.

- (416)
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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.

Composite - a Compound Element that consists of two or more distinct weaknesses, in which all weaknesses must be present at the same time in order for a potential vulnerability to arise. Removing any of the weaknesses eliminates or sharply reduces the risk. One weakness, X, can be "broken down" into component weaknesses Y and Z. There can be cases in which one weakness might not be essential to a composite, but changes the nature of the composite when it becomes a vulnerability.

become a very small or negative number.
