Vulnerability from github – Published: 2026-02-28 02:48 – Updated: 2026-02-28 02:48

Summary

Hive has Double-free and Use After Free Vulnerabilities

Details

Drop implementation for Hive did perform free, but so did Hive::close, which, at the end of the scope performed Drop, therefore triggering double-free.

Additionally, function Hive::from_handle was not marked as unsafe, making it, in combination with as_handle easy to clone and trigger double-free in safe code or triggering UB when using invalid pointer.

Detection rules are retrieved from Rulezet.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
