Veelvoorkomende gevolgen

Bereik Impact Waarschijnlijkheid
OtherReduce Reliability

Note: This issue can prevent the product from running reliably, since the child might not perform essential destruction operations. If the relevant code is reachable by an attacker, then this reliability problem might introduce a vulnerability, such as a memory leak (CWE-401).

Notities kwetsbaarheidsmapping

Rechtvaardiging : This CWE entry is at the Base level of abstraction, which is a preferred level of abstraction for mapping to the root causes of vulnerabilities.
Opmerking : Carefully read both the name and description to ensure that this mapping is an appropriate fit. Do not try to 'force' a mapping to a lower-level Base/Variant simply to comply with this preferred level of abstraction.
