CWE-826Premature Release of Resource During Expected Lifetime

Abstraction: Base · CVEs in our corpus: 10

The product releases a resource that is still intended to be used by itself or another actor.

This weakness focuses on errors in which the product should not release a resource, but performs the release anyway. This is different than a weakness in which the product releases a resource at the appropriate time, but it maintains a reference to the resource, which it later accesses. For this weakness, the resource should still be valid upon the subsequent access. When a product releases a resource that is still being used, it is possible that operations will still be taken on this resource, which may have been repurposed in the meantime, leading to issues similar to CWE-825. Consequences may include denial of service, information exposure, or code execution.

MITRE ATT&CK techniques this weakness enables

Our own two-way CWE↔ATT&CK cross-walk — a direct mapping with no public source (the CWE→CAPEC→ATT&CK chain leaves most top weaknesses, incl. XSS and SQLi, mapped to nothing). Drafted by Grok and spot-checked by Claude Opus 4.8.

Direction: other covers this; this covers other (F/M/P = full / mostly / partial).
